Review on cobalt ferrite as photo-Fenton catalysts for degradation of organic wastewater

Abstract

In the era of rapid global industrialization, the problem of water pollution around the world has become an increasingly serious and urgent problem. Photo-Fenton catalysis has attracted extensive research as...

Cd0.9La0.1S/graphdiyne type-II heterojunction structure for efficient photocatalytic hydrogen production

“…Moreover, it demonstrates the good hydrogen production capability of CLGY-20% by comparing with other GDY-based photocatalysts for hydrogen production (Table 1). [46][47][48][49][50] Fig. 5…”

Review of Piezocatalysis and Piezo-Assisted Photocatalysis in Environmental Engineering

“…Photocatalysis is a process of solar energy conversion [26]. It involves the use of light energy to activate a photocatalytic material that has mostly been explored as semiconductors such as TiO 2 [5], BiVO 4 [27], spinel compounds [28], metal-free materials such as g-C 3 N 4 [29], and recently developed natural materials such as pollen [30,31]. Electron-hole pairs are generated in both the material bulk and surface under solar irradiation.…”

Two‐Dimensional BiOBr Nanosheets Coupled with FeOOH Quantum Dots as Composite Photo‐Fenton Catalysts for Organic Pollutant Degradation under Visible Light

“…The Fenton oxidation technology reported by Henry J. in 1894 showed excellent performance in the advanced treatment of organic pollutants. In this process, H 2 O 2 is activated by Fe 2+ to generate strong oxidizing ⋅OH, which can non‐selectively attack refractory organic molecules and mineralize into inorganic substances [11] . However, Fenton oxidation technology has limitations, [12] such as: (1) the optimum pH of the reaction system is 2–3; (2) the Fe 2+ regeneration rate is low.…”

“…In this process, H 2 O 2 is activated by Fe 2 + to generate strong oxidizing * OH, which can non-selectively attack refractory organic molecules and mineralize into inorganic substances. [11] However, Fenton oxidation technology has limitations, [12] such as: (1) the optimum pH of the reaction system is 2-3; (2) the Fe 2 + regeneration rate is low. In view of the above deficiencies, researchers proposed the heterogeneous Fenton reaction [13] and combined the Fenton technology with other AOPs to improve the performance of the catalyst.…”
