摘要:
Provided is a catalyst material comprising aggregates of nanoneedles of mainly R-type manganese dioxide and having a mesoporous structure. With this, water can be oxidatively decomposed under visible light at room temperature to produce oxygen gas, proton and electron. Also provided is a catalyst material comprising aggregates of nanoparticles of mainly hydrogenated manganese dioxide. With this, acetic acid or an inorganic substance can be synthesized from carbon dioxide gas.
摘要:
Provided is a tritium adsorbent. Use of hydrogen- or lithium-containing manganese oxide having a spinel crystal structure as a tritium adsorbent to trap tritium from tritium-containing water makes it possible to inexpensively separate tritium from water.
