Rationally Designed Mn0.2Cd0.8S@CoAl LDH S-Scheme Heterojunction for Efficient Photocatalytic Hydrogen Production
构建高效、稳定的异质结光催化剂体系是实现太阳能驱动分解水制氢的有效途径.本研究通过物理混合法将Mn0.2Cd0.8S纳米棒与CoAl LDH纳米片进行耦合,成功制备出一种新型的Mn0.2Cd0.8S@CoAl LDH(MCCA)S型异质结光催化剂.光致发光光谱和光电流测试结果表明,该异质结在内建电场的作用下可以有效地加快Mn0.2Cd0.8S和CoAl LDH界面间光生载流子的分离和电子转移.关键的是,CoAl LDH的引入有效地抑制了光生电子与…查看全部>>
Constructing an efficient and stable heterojunction photocatalyst system is a promising approach to achieve solar-driven water splitting to produce hydrogen.In this work,a novel Mn0.2Cd0.8S@CoAlLDH(MCCA)S-scheme heterojunction was successfully prepared through the efficient coupling of Mn0.2Cd0.8S nanorods and CoAl LDH nanosheets,employing a physical mixing method.The photoluminescence and photocurrent-time response results demonstrated that the internal ele…查看全部>>
