Synergy Derived from Bimetal Co−Cu in Phosphate to Enables Ultrafast Catalytic Hydrogenated Activity in Nitrophenol Reduction

Abstract

Herein, we report Co−Cu bimetal integrated phosphate catalyst, unexpectedly enables ultrafast catalytic reduction of 4‐nitrophenol within 40 s by right of the synergy of bimetals. Impressively, the reaction induction period observed might indicate the deoxygenation of metal oxide units in phosphate, however, which was eliminated using bimetal (Co−Cu) phosphate at 30 °C and 40 °C. The calculated reaction rate constant is 4.78 min−1 at 30 °C, which exhibits a very high superiority compared to other reported cobalt‐based catalysts. This study offers the possibility for the ultrafast catalytic reduction and elimination of toxic nitrophenol using efficient‐cost transition metal catalysts.

Fabrication and Characterization of Heterogeneous Sheet‐like Mesoporous Cu3(PO4)2⋅3H2O Catalysts and Selective Catalytic Oxidation of Styrene

“…Additionally, the O 1s′ XPS spectra in Figure 4b exhibits a single major peak at 530.8 eV, which is attributed to P−O in Cu 3 (PO 4 ) 2 ⋅ 3H 2 O. Therefore, according to all the above characterization results, we can basically determine the successful synthesis of Cu 3 (PO 4 ) 2 ⋅ 3H 2 O [32] …”

“…Therefore, according to all the above characterization results, we can basically determine the successful synthesis of Cu 3 (PO 4 ) 2 ⋅ 3H 2 O. [32] Catalytic selective oxidation of styrene Styrene oxide, a crucial organic intermediary for the creation of valuable products including epoxy resins, paints, and surfactants, is produced via the selective epoxidation of styrene in recent years. [33] Despite numerous tries, the majority of studies are unable to provide the epoxide product with high conversion and high selectivity at the same time.…”

Route‐Optimized Synthesis of Bagasse‐Derived Hierarchical Activated Carbon for Maximizing Volatile Organic Compound (VOC) Adsorption Capture Properties

“…The service life of the adsorbent acted as assessment criteria of industrial value [49–51] and was further evaluated through testing repeated adsorption and desorption cycles of benzene and toluene on BC‐1 for knowing its adsorption stability. We performed four continuous cycles of the adsorption process and collected the adsorption isotherms of benzene and toluene.…”
