Insight into the whole characteristics of (Pd/WP)/CdS for photocatalytic hydrogen evolution

Engineering of a hierarchical S-scheme 2D/3D heterojunction with graphdiyne (g-CnH2n−2) coated 3D porous CoAl2O4 nanoflowers for highly efficient photocatalytic H2 evolution

“…As a result, it allows for the determination of the electron transfer pathway between GDY and CoAl 2 O 4 . 50 As illustrated in Fig. 10a and b, the work functions of GDY and CoAl 2 O 4 are determined using the formula Φ = hν – ( E Fermi – E Cutoff ), where hν represents the photon energy, E Fermi is the high kinetic energy starting edge, and E Cutoff is the low kinetic energy cutoff edge (with hν = 21.22 eV), whose values are calculated to be 6.59 eV for GDY and 4.40 eV for CoAl 2 O 4 , respectively.…”

A review of g‐C3N4‐based photocatalytic materials for photocatalytic CO2 reduction

“…The cocatalyst itself is inactive, but it possesses an outstanding ability to capture photogenerated carriers (the reduction-type cocatalyst can capture photogenerated electrons, while the oxidation-type cocatalyst can capture photogenerated holes), which is beneficial to improve the efficiency of photogenerated carrier separation and migration of g-C 3 N 4 . [96][97][98] In addition, the cocatalyst can serve as an active site with a low reaction potential barrier, which facilitates the improvement of product selectivity and yield. Until now, various cocatalysts have been explored to enhance the photocatalytic CO 2 reduction performance of g-C 3 N 4 .…”

Synthesis, Structure and Light‐Driven H2 Production of a {Ti21} Titanium‐Oxo Cluster Featuring Pentagonal {Ti(Ti5)} Motifs

“…In order to solve the problems of energy shortage and environmental pollution, people have gradually begun to pay attention to the conversion of solar energy into chemical energy with extensive research. [1][2] Photocatalytic hydrogen production by water splitting can effectively reduce carbon dioxide emissions, which will provide a practical solution to the global energy crisis and has broad application prospects. [3][4] Photocatalysts play an important role in the process of water reduction reaction, so people started to explore a variety of efficient and low-cost semiconductor photocatalysts.…”
