Heterogeneous
photocatalysis has captured worldwide attention because
of its tremendous potential in the field of solar energy conversion
to solve energy and environmental issues. Efficient utilization of
solar energy is always the target of our pursuit in the areas of photocatalysis.
The design of appropriate photocatalysts for wide-range light harvest
from ultraviolet to near-infrared regions is a promising way to realize
the practical utilization of photocatalysis. To date, the exploration
of NIR light-responsive photocatalysis includes sensitization with
near-infrared light (NIR) responsive materials such as dye molecules
and black phosphorus, the surface plasmon resonance effect, upconversion,
and narrow band gap materials as NIR harvesters. This review gives
a comprehensive discussion and summary on the latest developments
of the design and engineering of NIR-active photocatalysts and the
related photocatalytic system for various environmentally friendly
photoreactions including environmental remediation, water splitting,
CO2 reduction, nitrogen fixation, and selective organic
transformations. Finally, the future perspectives and challenges are
present at the end in order to give a comprehensive understanding
about the present near-infrared-driven photocatalysis and the promising
directions for future investigations.
Photocatalytic oxidation of alcohols with high selectivity is a promising approach for the synthesis of organic compounds under mild conditions and for solar energy conversion. In this work, we report on the highly selective anaerobic photooxidation of alcohols to carbonyl compounds with coupled H2 production over Pt‐loaded Fe‐doped SrTiO3 under visible light. Representatively, an optimized apparent quantum efficiency of 13.2 % at 420 nm was obtained for benzyl alcohol oxidation. X‐ray absorption fine structure and in situ diffuse reflectance IR spectroscopy revealed that the surface oxygen vacancies and the fine‐tuned valence band edge position induced by Fe doping not only contributed to the activation of α‐C−H bonds in alcohols, but also avoided the over‐oxidation of the obtained carbonyl compounds.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
