Abstract
【解決手段】有機廃水処理に用いる電極を構成する触媒組成物であって、触媒と、薄片化黒鉛と、バインダと、を備え、触媒として、窒素を含有する炭素質材料を含み、薄片化黒鉛100質量部に対する触媒の含有量は、10質量部以上50質量部以下である。
【選択図】図1
Description
カソード103に用いる触媒組成物について説明する。
O2 + 4H+ + 4e− → 2H2O …反応式(2)
窒素含有炭素質材料は、少なくとも炭素の網目構造の中に窒素を含んでいる構造を有しており、その窒素近傍で酸素還元反応が進行すると考えられている。形状は、不定形である。
黒鉛が得られることから、結晶性の良好な鱗状黒鉛又は鱗片状黒鉛が好適である。
アノードの基材としては、微生物を定着しやすく、有機物を分解して発電した際の電子を効率よく伝導できる媒体が望ましい。例えば、カーボンクロス(炭素織布)、カーボンペーパー、カーボンフェルト、ポーラスカーボン、金属メッシュ、金属メッシュにカーボンブラック又は炭素繊維をコーティングした部材などが適している。
本実施形態に係る触媒組成物の製造方法は、触媒を製造する触媒製造工程と、触媒と薄片化黒鉛とバインダとを混合し、触媒組成物を製造する触媒組成物製造工程と、を含む。
実施例1の薄片化黒鉛を加えなかったことを除いて、実施例1と同様の手順で製造した。
実施例1の薄片化黒鉛を20gに変えたことを除いて、実施例1と同様の手順で製造した。
(比較例3)
実施例1の薄片化黒鉛を1.7gに変えたことを除いて、実施例1と同様の手順で製造した。
比較例1のスチレンブタジエン樹脂を含むバインダ溶液を3.6gの20%ナフィオン溶液(「ナフィオン」は登録商標)に変えたことを除いて、比較例1と同様の手順で製造した。
実施例1、2、3、4、5および比較例1、2、3、4で得られた触媒組成物を含む電極について標準的な3電極セルを組み、電位走査によりそれらの電極に電気化学的な負荷を加速的に与え、そのときの酸素還元活性を回転ディスク電極法により評価した。ここで、特許文献1にも記載されているように、微生物燃料電池の電極は、硫酸酸性下で使用される。この点を考慮し、耐久性の試験は、後述のとおり、硫酸水溶液中に電極を浸漬した条件で行った。
