“…The photosensitization of InVO 4 by In 2 S 3 and enhanced charge separation through the compact interface junction between semiconductors significantly promoted photocatalytic activity of In 2 S 3 /InVO 4 . Huang et al ( 2019 ) also synthesized a series of different hierarchical heterojunctions, including g-C 3 N 4 /BiOI (type I), g-C 3 N 4 /Bi 4 O 5 I 2 (type I), and g-C 3 N 4 /Bi 5 O 7 I (type II) using direct precipitation and in situ calcination transformation (Fig. 2 b–d).…”

“…However, electrons and holes are enriched on the same semiconductor, which cannot effectively restrain the recombination of photoinduced electrons and holes. This makes type I semiconductor heterojunctions questionable prospects for photocatalytic property improvement [288] , [289] . To date, large numbers of traditional type II heterojunctions have been intensively investigated, some of which have rendered drastically optimized photocatalysis performances.…”

“…Single component photocatalysts fail to exhibit higher photocatalytic efficiency due to the rapid recombination of the photogenerated charge carriers. In order to achieve enhanced photocatalytic efficiency, one of the most common strategies is to construct a heterojunction photocatalytic system by coupling two or more semiconductors [234]. Typically, in a heterojunction photocatalytic system, the photogenerated electrons in the CB of photocatalyst A migrate to the CB of photocatalyst B, while the photogenerated holes in the VB of photocatalyst B move to the VB of photocatalyst A, curbing their recombination due to spatial isolation.…”
