Hydrogen peroxide (H2O2) plays
an essential
role in many industrial fields and is globally listed as one of the
indispensable chemicals. However, synthesizing H2O2 using the anthraquinone oxidation (AO) process requires multiple
steps and releases hazardous organic compounds, which could seriously
lead to many environmental and human health-related problems. Therefore,
an urgent need for manufacturing H2O2 using
green and sustainable methods to deal with the mentioned issues has
enormously captured scientific interest. In this circumstance, the
integration of piezo and photo effects on the generation of H2O2 from water and oxygen with the requirements
of using low-cost and efficient catalytic materials is majorly considered.
Herein, we report a simple and efficient way to produce H2O2 by employing modified graphitic carbon nitride (g-C3N4) catalysts to achieve the targets. The nanostructured
materials were intensively characterized to deeply understand how
the catalysts work to produce a significant amount of H2O2, reaching up to 1147.03 μM within 1 h irradiation.
The findings showed that the fabrication of novel metal–carbon
bonds and other functional groups could be responsible for adding
more active sites in the system, promoting the enhancement of catalytic
activities. This work would offer scientists a novel outlook to design
and develop carbon-based materials for producing fine chemicals from
catalysis and other applications.
Doping is an efficient technique to regulate and modify the structures of carbon-based materials. In this study, we explored the potential roles of doping precursors in generating H2O2 from oxygen and water under piezo-photocatalytic effects.
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.
