Description
Al+3H2O →Al(OH)3 +(3/2)H2 (1)
2Al(OH)3 →Al2O3 +3H2O (2)
これらの反応は、アルミニウム又はアルミニウム合金の表面で起こる反応であるが、本発明の水素発生材料に係る摩擦腐食反応では、さらに、
3Al+3H2O →Al2O3 +AlH3+(3/2)H2 (3)
Al(OH)3 +AlH3→Al2O3 +3H2 (4)
の反応が期待される。(3)の反応は、表面反応ではなく、アルミニウム結晶の内部、特にクラック部で起こるバルク反応であり、多量の水素を製造するためのメカノケミカル腐食反応に寄与する。また、(4)の反応は、表面反応とバルク反応との境界で生ずる界面反応と考えられる。(3)及び(4)の反応が、本発明を特徴づける水素ガス生成の反応機構である。
Al +(3/2)H2O→(1/2)Al2O3+(3/2)H2 (5)
の化学反応になる。したがって、アルミニウム材1モル(27g)と水1.5モル(27g)を原料として、アルミ酸化物(アルミナ)0.5モル(51g)と水素ガス1.5モル(3g、33.6リットル)を製造できることが分かる。
Claims (1)
- 水を分解して水素を発生する水素発生材料の製造方法であって、
アルミニウム又はアルミニウム合金を水中で摩擦、粉砕し、50μm以下の微粒子にする工程と、
前記微粒子に温度又は超音波の衝撃を加える活性化処理を行い、数日間の室温における熱処理を施した後、前記微粒子を5°Cに冷却して保存状態に置く工程と、
を含むことを特徴とする製造方法。
