Global warming and ecological degradation are becoming major environmental problems in the world today. To reduce energy loss advocate green chemistry, development of new sources is very important. Electrocatalytic technology has low pollution carbon emission because only electrons involved there no need to add external fuel. And metal-organic framework (MOF), with its porous structure large surface area, can provide an ideal reaction platform for electrocatalytic reactions. This paper first introduces discovery MOF materials, followed by a discussion current methods designing MOFs from several perspectives, including pore size, conductivity, active sites. Then materials transition metal ions was analysed perspective elements Fe, Co, Ni, which exhibit higher rates comparison ordinary hydrogen precipitation reaction, oxygen absorption other Finally, this introduced synthetic ideas reviewed synthesise materials.

Abstract In this work, the optimal efficiency and mechanism of action CoO activated sodium percarbonate (SPC) for degradation Reactive Blue 19 was investigated. The three-factor interaction SPC concentration, dosage initial pH effects factors such as anions humic acids (HA) were results show that CoO/SPC system (93.8%, 0.01015 min− 1) efficiently degraded RB19 also suitable other organic dyes (32.7%~100%) antibiotics (97.1%~100%). During activation by CoO, carbonate radical (CO3•−), hydroxyl (•OH), superoxide (O2•−) singlet oxygen (1O2) are involved in process, among which CO3•− (88.2%) plays an indispensable role, proved quenching experiments electron paramagnetic resonance (EPR) tests. Co2+ dissolution lower than 150 µg/L, meets emission standard (1 ppm); application avoids problem acidification wastewater, final product is green color. This study presents a novel approach to treating dye wastewater combining transition metal oxides with percarbonate.

Abstract BACKGROUND Anthraquinone dyes have an anthraquinone structure as their nucleus, with one or more substituents forming different organic dyes. a complex that allows them to exist stably in water environment, but also makes toxic than azo This results varying degrees of harm both humans and the environment result residual on material’ surface. Sodium percarbonate (SPC) is highly promising oxidant due its green end product. Therefore, this study, catalytic performance kinetic study cobalt oxide (CoO) SPC under conditions were systematically investigated using RB19 target pollutant. The Box–Behnken Design (BBD) model was used degradation by CoO/SPC system, which gives basis for practical application. types reactive oxygen species effectively degrade potential mechanism system revealed. At same time, evaluated terms practicality. RESULTS In work, activation CoO towards blue 19 (RB19) explored. Experimental showed nearly 93.8% could be removed within 30 min 1 mmol L −1 mg CoO. three‐factor interaction effects concentration, dosage initial pH investigated. BBD set up obtain optimum working 1.039 SPC, 33.35 7.82, gave rate 95.372%. Additionally, it confirmed solubility Co 2+ consistently <150 μg , meeting emission standard (1 ppm). presence Cl − NO 3– HA had similar profile, slight promoting effect small amounts inhibitory when introduced excess. introduction SO 4 2– negligible degradation, whereas HCO 3 produced effect. Furthermore, PO strong suitable other (32.7%–100%) antibiotics (97.1–100%). Electron paramagnetic resonance (EPR) analysis quenching experiments relative contribution free radicals CO •‐ (88.12%) >O 2 (51.11%) >1O (37.21%) >•OH (5.27%) > (3.33%) >CoO (0.09%). It has been activates through electron transfer. CONCLUSION present describes less time‐consuming, efficient method treating dye wastewater requires oxidizer catalyst, making economical. proposes straightforward, cost‐effective technique triggered transition metal oxides. © 2024 Society Chemical Industry (SCI).
