Controllable photodeposition of nickel phosphide cocatalysts on cadmium sulfide nanosheets for enhanced photocatalytic hydrogen evolution performance

Abstract

As efficient cocatalysts in photocatalytic processes, transition metal phosphides are usually synthesized in harsh and tedious conditions. So to achieve their simple and controllable loading on photocatalyst surface is especially valuable.

The synergy of in situ-generated Ni0 and Ni2P to enhance CO adsorption and protonation for selective CH4 production from photocatalytic CO2 reduction

“…Compared to CN, the increased visible light absorption of Ni 2 P/CN- x is attributed to the intrinsic absorption of Ni 2 P. 43 There is a slight red shift in the absorption edge of Ni 2 P/CN- x , an indication of narrowing of the band gaps ( E g ) of Ni 2 P/CN- x from that of CN. 44 The band gaps of CN, Ni 2 P/CN-0.3, Ni 2 P/CN-0.5 and Ni 2 P/CN-1 were calculated to be 2.60 eV, 2.54 eV, 2.50 eV and 2.46 eV, according to the plots of ( αhν ) x ( x = 2) vs. band energy ( hν ). 45 As shown in Fig.…”

Optimized hot electron injection from Cu nanoparticles to S-doped C3N4by the formed S–Cu bonds for an enhanced photocatalytic performance

“…For SCN-Cu and CN-Cu, no Curelated peak appears due to their amorphous characteristics, and the peak weakness at 27.31 is mainly due to the shielding effect of photo-deposited Cu NPs. 28 For SCN-Cu/Pt, the patterns of face-centered-cubic Pt NPs can be observed (Fig. S3a, ESI †).…”

Red Phosphorus: An Up-and-Coming Photocatalyst on the Horizon for Sustainable Energy Development and Environmental Remediation

“…Ni-based materials, in particular, have demonstrated superb photocatalytic activities as H 2 -evolution cocatalysts, garnering massive interests from the photocatalysis community to further propel the study and development of Ni-based cocatalysts to greater heights. A cornucopia of Ni-based materials has been identified as highly promising cocatalysts with fascinating semiconducting properties, namely sulfides, , phosphides, , oxides, , hydroxides, , and molecular complexes. , Ni and Ni-related compounds have made a name for themselves in a broad range of heterogeneous and homogeneous photocatalysis due to their brilliant capability to form complexes by adopting several oxidation states. More importantly, Ni-based materials are strikingly less expensive as compared to noble metal materials thanks to their earth abundant nature, making them ideal candidates in lieu of noble metal catalysts for a wide variety of photocatalytic and energy applications .…”
