Abstract
SHS investigation development is considered from the geographical and historical viewpoint. 3 stages are described. Within Stage 1 the work was carried out in the Department of the Institute of Chemical Physics in Chernogolovka where the scientific discovery had been made. At Stage 2 the interest to SHS arose in different cities and towns of the former USSR. Within Stage 3 SHS entered the international scene. Now SHS processes and products are being studied in more than 50 countries.
Abstract
Modern artificial heterostructures control redox reactions at the catalyst's
active sites by effectively separating charges and transporting excitons with the help of
light sources. Regarding environmental remediation, the Z-scheme—particularly in the
degradation and mineralization of organic pollutants—plays a crucial role.
Appropriately designed photocatalysts with Z-scheme have several benefits over
conventional photocatalytic processes, including improved charge separation and
effective redox process management in response to visible light. It provides the way for
the creation of newer and more effective photocatalysts because it is said to make
reduction and oxidation processes easier than with the constituent single precursor. In
contrast to other heterostructure schemes like the Type-I and Type-II schemes,
heterostructures with the Z-scheme mechanism attracted a lot of attention.
