Constructing 1D/2D Schottky-Based Heterojunctions between Mn<sub>0.2</sub>Cd<sub>0.8</sub>S Nanorods and Ti<sub>3</sub>C<sub>2</sub> Nanosheets for Boosted Photocatalytic H<sub>2</sub> Evolution

Abstract: Sustainable photocatalytic H2 evolution has attracted extensive attention in recent years because it can address both energy shortage and environmental pollution issues. In particular, metal sulfide solid-solution photocatalysts have been widely applied in photocatalytic hydrogen generation owing to their excellent light harvesting properties, narrow enough band gap, and suitable redox potentials of conduction and valance bands. However, it is still challenging to develop low-cost and high-efficiency sulfide s… Show more

“…6(d), the arc radius of the CdS/MoS 2 /rGO nanocomposites was smaller than that of pure CdS, which suggested a decrease in the interface layer resistance and charge‐transfer resistance on the surface. These outcomes further confirmed the enhancement of conductivity and charge separation ability upon the addition of MoS 2 /rGO 45,46 …”

“…As is exhibited in Fig. 7a, Mn0.2Cd0.8S showcases the strongest PL intensity under excitation wavelength at 390 nm, which could attribute to its intrinsic bondto-bond recombination 40 . It is believed that the strong fluorescence intensity symbolizes abundant ground state electrons which result in the recombination of e − and h + , further result in a decline of photogenerated electron participating in photocatalytic H2 production 41,42 .…”

“…Semiconductor-based photocatalytic technology is one of the most promising strategies for solving the ever-increasing energy crisis and addressing environmental pollution as well as concerns for public health [1][2][3][4]. Although numerous efforts have been made since the pioneering work on TiO 2 photoelectrodes for water splitting in 1972 [5][6][7], the industrialization of this technology is still unrealized due to its inefficiency and problems with implementation. In general, the photocatalytic conversion efficiency is influenced by light absorption, photogenerated carrier separation and surface reduction-oxidation reactions.…”
