CdS/ZnIn₂S₄ type II heterojunctions improve photocatalytic hydrogen production: faster electron–hole separation and wider visible light utilization

Abstract

It is well known that the efficiency of electron-hole separation and visible light utilization are the main reasons affecting the photocatalytic performance. In this work, ZnIn2S4 (ZIS) is modified with...

Interfacial phosphate-like “bridge” mediates bulk charge and surface oxygenated-intermediate migration for efficient photoelectrochemical water splitting

“…The binding energy was also positively shifted for the ZIS–P/CdS sample, which was possibly initiated by the uneven charge distribution. 21–23 A similar shift occurred in the S 2p 3/2 and 2p 1/2 orbits (Fig. S2b, ESI†).…”

Synthesis of lamellar O-doped ZnIn2S4 on layered g-C3N4 for boosted charge transfer and photocatalytic performances

“…11 Among these ultrathin 2D NS materials, ZnIn 2 S 4 (ZIS) has been recognized as an outstanding photocatalyst owing to its favorable stability, suitable band gap, and superior visible-light responsive capability. [12][13][14][15] Nevertheless, its photocatalytic activity is unsatisfactory with practical application due to the quick recombination of charge carriers. 16 Therefore, many tremendous endeavors have to overcome the above drawbacks, such as elemental doping 17,18 and heterojunction creation.…”
