Photocatalytic Evolution of Hydrogen Peroxide: A Minireview

Hydrogen peroxide (H2O2) has demonstrated applicability in a wide range of applications, spanning from bleaching agent the pulp industry, environmental remediation, and fuel cell technology. Industrial scale synthesis, either by anthraquinone method or catalytic oxidation hydrogen gas, serious drawbacks which are related with energy demanding multi-step processes. An alternative green strategy involves photocatalytic synthesis H2O2. All that is needed renewable sun, semiconducting species absorbing visible region, water, oxygen. In this minireview, we describe evolution research milestones have been achieved within recent decades regarding development functional systems. early studies, back 1980’s, TiO2-based systems were mostly investigated. However, due to large band gap titania (3.2 eV), semiconductors studied strongly absorb region. Thus, variety semiconductor families investigated, such as doped systems, other metal oxides, sulfides, organic semiconductors, metal-organic frameworks, carbon nitride etc. parallel, dopants onto surface main lead both inhibition electron-hole recombination H2O2 degradation. The current minireview collectively provides studies higher production rates offer some suggestions for near future.
