CO during the treatment of organic wastewater 2 Usually the final degradation product, causes a certain waste of carbon resources, and is unfavorable for improving the increasingly serious greenhouse effect. Therefore, in the continuous photocatalytic oxidation-reduction process, namely a two-in-one self-circulation system, organic pollutants are used as hole sacrificial agents in CO 2 The photo-generated electrons are efficiently utilized in the reduction process, and considerable photocatalytic performance can be obtained. Therefore, the self-recovery strategy is used in the two-in-one system, so that not only can the organic pollutants be degraded, but also the final CO can be obtained 2 Reduction of the product to CO fuel is an attractive strategy. However, in order to mineralize organic pollutants and simultaneously CO 2 Reduction to CO requires development of a photocatalytic material having excellent photooxidative degradation and photoreduction properties.
CdS photocatalysts generally have a wide visible light absorption range and a sufficiently negative potential at the conduction band edge, which is an important material for the development of photocatalytic technology. Many efforts have been made to further improve the stability, migration and utilization efficiency of CdS photogenerated carriers. However, exploring an effective strategy to improve the photocatalytic performance of CdS remains a significant challenge. The use of heteroatom doping strategies to tailor the band position and charge density distribution of CdS has proven to be a very promising strategy. In addition, inUnder the effect of heteroatom doping, abundant S vacancies can be obtained in the metal sulfide, and the photocatalytic activity is further promoted. Notably, cerium (Ce) has a value between Ce 3+ And Ce (Ce) 4+ The low redox potential in between is typically used as a heteroatom to modulate the photocatalytic properties of the semiconductor material. In addition, water is CO 2 A rate determining step of reducing the S vacancy by lowering the energy barrier of the intermediate conversion to H 2 Plays an important role in O decomposition. At present, the proposal that the Ce doped CdS photocatalyst is used for photocatalytic mineralization of organic matters and continuous preparation of fuel is not reported.

Thereby efficiently mineralizing tetracycline pollutants and CO in the two-in-one self-circulation photocatalysis system 2 Reducing to CO. By CO 2 The self-supply system produces CO gas fuel with near perfect selectivity, which provides a concept for further treatment of sustainable organic pollutants and carbon resource recovery.

FIG. 1 (a) is an XRD pattern of pure CdS, ce1-CdS, ce2-CdS, ce4-CdS, and Ce8-CdS composite photocatalyst, and characteristic peaks of all samples are in hexagonal system CdS (JCPLS No. 41-1049). It is difficult to identify the characteristic peaks of Ce in the XRD spectrum, probably because Ce in CdS exists in the form of ions. While the peak intensity at 26.5 ° ((101) plane) of all Ce-CdS samples gradually decreased with increasing Ce content, indicating that Ce doping changed the crystal structure of CdS, resulting in a certain concentration of S vacancies. FIG. 1 (b) shows electron paramagnetic resonance spectra of pure CdS, ce1-CdS, ce2-CdS, ce4-CdS, and Ce8-CdS composite photocatalyst. As the Ce doping amount increases, the peak intensity at g=2.003 gradually increases, indicating that the S vacancy concentration also gradually increases, compared to pure CdS. Thus, by doping of cerium metal, there are abundant S vacancies in CdS, which will help to increase H 2 Dissociation activity of O molecules and reduction of CO 2 And a reduction reaction energy barrier.

FIG. 3 is a UV-vis diagram of (a) pure CdS and Ce4-CdS composite photocatalyst; (b) band gap diagram of pure CdS and Ce4-CdS composite photocatalyst. The light absorption capacity and band structure of pure CdS and Ce4-CdS were studied by UV-vis DRS. As shown in FIG. 3 (a), the calculated band gap was about 2.37eV (FIG. 3 (b)) with the light absorption edge of pure CdS at 560 nm. In contrast, ce4-CdS has a significant red shift in the visible region. In addition, the band gap of Ce4-CdS is also reduced (2.35 eV), which shows that the energy band of CdS can be effectively regulated by Ce doping, and also shows that the Ce4-CdS can absorb solar energy more effectively and generate CO for photo-reduction 2 Is a single electron.
FIG. 4 is a plot of photocurrent response (a), impedance plot (b), steady state fluorescence plot (c) and transient fluorescence plot (d) for pure CdS and Ce 4-CdS. As shown in fig. 4 (a). The photocurrent response of pure CdS and Ce4-CdS both show different degrees of photocurrent response intensity at the moment of lamp turn-on. The photocurrent density of Ce4-CdS is 6 times that of pure CdS, which shows that the doping effect of Ce and the existence of S vacancy improve the photogenerated charge separation efficiency of Ce 4-CdS. Similarly, EIS was used to evaluate interfacial charge transfer (b of fig. 4). As expected, the Ce4-CdS composite material exhibited a smaller semi-circular radius. This is due to the doping of Ce to produce a large amount of Ce 3+ /Ce 4+ Site, ce 3+ /Ce 4+ The sites not only can capture a large amount of photo-generated electrons, but also can be used as active sites to participate in CO 2 Thus improving the charge transfer mode in Ce4-CdS and reducing the surface resistance. Furthermore, the steady state photoluminescence spectrum of pure CdS showed a strong emission peak at 428nm, whereas the intensity of Ce4-CdS with a large number of S vacancies was significantly reduced, indicating that Ce doping and induced S vacancies helped to suppress recombination of photogenerated carriers (c of fig. 4). In FIG. 4 (d), the lifetimes of pure CdS and Ce4-CdS are fitted by a double exponential decay function. τ 1 And τ 2 Corresponding to radioactive and non-radioactive energy transfer, respectively. Ce4-CdS has smaller τ than pure CdS 1 And a larger τ 2 Ce doping is shown to act as a good electron capture site, and can extend photoelectron lifetime through non-radiative quenching.
Photocatalytic mineralization of organic pollutants and reduction of CO by prepared materials 2 The performance was evaluated by a self-made two-in-one self-circulating photocatalytic system. The photocatalyst and the aqueous solution of the organic contaminant were mixed, and after passing high purity Ar gas through the reactor for 30min, the reactor was closed. The light source is provided by a 300W xenon lamp. After illumination for a fixed time, the gas product is detected by gas chromatography, and the corresponding yield of CO can be obtained by bringing the result into a standard curve. The concentration of the organic contaminant is detected by an ultraviolet spectrophotometer.
