Boosting full-spectrum light driven surface lattice oxygen activation of ZnMn2O4 by facet engineering for highly efficient photothermal mineralization of toluene

Facet-Controlled Synthesis of Mn3O4 Nanorods for Photothermal Synergistic Catalytic Oxidation of Carcinogenic Airborne Formaldehyde

“…Only when the temperature is high enough can thermal catalysis become the dominant mechanism, where photocatalysis is beneficial to lowering the activation energy of thermal catalytic oxidation. On the other hand, Zhang’s group , believed that the activation of surface lattice oxygen by light actuation is crucial for the photothermal catalytic oxidation of VOCs. In light-driven catalytic oxidation, the light absorption and photothermal effect contribute to the local high temperature in the interior of catalysts, which can effectively enhance the activation ability of surface lattice oxygen into surface active oxygen and accelerate the exchange of surface lattice oxygen and gaseous oxygen.…”

“…Photothermal catalysis is not just a simple superposition of photocatalysis and thermal catalysis, which can significantly enhance the reaction rate through the synergistic effect. For instance, Zhang’s group ,, conducted a series of studies on photothermal catalytic reactions, such as the catalytic oxidation of VOCs and the catalytic reduction of CO 2 . They found that the surface lattice oxygen activation of catalysts plays a significant role in the efficiency of a redox reaction.…”

Facet-Dependent Activity of Bismuth Bromide Nanosheets in Nonradical Fenton-like Catalysis

“…The nonradical catalytic pathways render the BiOBr-(001)/PMS system superior performance for selectivity degradation of electron-rich organic pollutants with good environmental robustness. − Its BPA degradation performance was hardly affected by most common environmentally relevant anions and was even promoted by bicarbonate (Figure a). Here, the bicarbonate-promoted activity of BiOBr-(010) for BPA degradation should be mainly due to enhanced PMS activation at alkaline pH, as demonstrated by the BPA degradation tests under different pH conditions (Figure c).…”

Removal of Formaldehyde and Its Analogues Using a Hybrid Assembly of Pyrene-Modified Hydrazide and rGO: A Negative Carbon Emission and Green Chemical Decomposition Method

“…29,30 Recently, it has been reported that the mineralization of volatile organic compounds can be achieved by increasing the catalytic activity of photothermal catalysts through surface lattice oxygen activation. 31,32 However, this method is mostly used for the removal of toluene and no application has been found for formaldehyde removal yet. 33 In contrast, the chemical reaction method can simply convert formaldehyde to non-toxic and non-harmful chemicals under mild reaction conditions.…”

“…Using plant’s absorption and physical absorption methods to remove formaldehyde is slow, non-specific, and less efficient. ,,, Catalytic oxidization is one of the chemical methods for formaldehyde decomposition. However, the complete decomposition of formaldehyde by catalytic oxidization creates ozone and other harmful chemicals. , Recently, it has been reported that the mineralization of volatile organic compounds can be achieved by increasing the catalytic activity of photothermal catalysts through surface lattice oxygen activation. , However, this method is mostly used for the removal of toluene and no application has been found for formaldehyde removal yet …”
