2019年11月1日 · In particular, cuprous oxide (Cu 2 O) is an intrinsically p-type narrow band gap semiconductor with a direct band gap of 2.0–2.2 eV and a CB potential at approximately −1.15 V, which makes it very suitable as a photocatalyst or co-catalyst for photocatalytic [9].

2020年5月15日 · Meanwhile, the decreased holes from the VB of Cu 2 O reduce the oxidation of Cu 2 O which contribute to the stability of WO 3 /Cu 2 O-30 min heterojunction. Furthermore, the separated photogenerated electrons and holes with high redox potential could quickly move to the surface and participate in the surface redox reaction of water.

2020年11月1日 · Cupric Oxide (CuO) is one of the most commonly used benchmark photocatalysts in photodegradation owing to the fact that they are cost-effective, non-toxic, and more efficient in absorption across a significant fraction of solar spectrum.

Cu 2 O has the advantages of abundant reserves, a low cost, and environmental friendliness. Based on the narrow bandgap and strong visible light absorption ability of Cu 2 O, Cu 2 O-based composite materials show infinite development potential in photocatalysis.

氧化亚铜 (Cu2O)是一种天然的p型半导体，具有2.0 eV的窄带隙，- 14.7 mA cm-2的高理论光电流密度，18%光转换效率，适当的导带位置 (比氢电位高0.7 V)，同时资源丰富，成本低。 所有这些优点使其成为PEC产氢最有前景的光电阴极之一。 然而，基于Cu2O的光电阴极材料仍然存在严重的光腐蚀和表面电子-空穴快速复合的问题，使得其在PEC裂解水的实际应用中仍面临着严重的稳定性和效率低下的问题。 为了缓解上述局限性，我们提出了一种简单的原位包覆策略，用氢取 …
