Anode graphite was recovered from a spent lithium ion battery (LIB) and reutilized as a carbon precursor to obtain graphene-based materials. Characterization results revealed that impurities were removed from the obtained graphite powder by cleansing processes. The as-synthesized reduced graphene oxide (rGO) from the purified graphite (LIB-rGO) dem...
In this study, three different Ag micro/nano leaves were successfully synthesized through a galvanic displacement reaction by adjusting the concentration of Ag+. The catalytic activities of the prepared Ag micro/nano leaves toward ORR showed strong dependence on their morphology. An optimal concentration of Ag+ can result in a well-defined Ag micro...
Cactus-like amorphous alumina microspheres (CA-AlOx) were fabricated by a facile solvothermal method without templates. The as-prepared CA-AlOx material exhibited the amorphous structure which is beneficial to the large specific surface area, developed pore structure, abundant functional groups and high reactivity of coordinatively unsaturated Al s...
By combining the prominent advantage of directional fluid flow in an internal airlift loop reactor with the cheap cost of liquid-solid separation in a hydrocyclone, a new slurry reactor for process intensification integrating solid catalytic reactions with liquid-solid separation for clear liquid products is proposed and designed to cut down the ca...
The aim of the present study is to develop an effective production process for a, omega-dodecanedioic acid (DC12) biosynthesis using n-dodecane and hydrolysate of Candida cells as substrates by membrane integrated repeated batch fermentation. Cells and n-dodecane were simultaneously recycled during the filtration of fermentation broth (FB) with a 1...
Vanadium oxy-acetylacetonate (VO(acac)(2)) was originally explored as an organic anode material for lithium-ion batteries (LIBs) with high capacity and rate performance. Specifically, the prepared VO(acac)(2) has delivered capacity of 620 mA h g(-1) at current density of 100 mA g(-1) with nearly 100% coulombic efficiency during cycling. Furthermore...
In recent years, activated carbon technology has been applied in various industrial flue gas purifications, with a high desulfurization efficiency but a relatively low denitrification efficiency. To strengthen the denitrification performance and further clarify which physicochemical property factor dominates the reduction of NO over activated carbo...
Low molecular weight (LMW) chitin exhibits antimicrobial activity, and its preparation generally employs high molecular weight chitin as raw material. Here we use raw crab shell as material to isolate LMW-chitin. The raw crab shell was treated with hydrochloric acid under different conditions, and the demineralization and deproteinization of acid t...
Highly crystalline, high-purity beta-SiC whiskers were successfully synthesised from a mixed sol of coal fly ash (CFA) and water glass (a silicon resource), and activated carbon (a carbon source) in a carbothermic reduction. The efficiency of the process is over 70%. The alkali activation effects of the water glass on CFA were characterised by FTIR...
Nanostructure-derived interfacial effect plays a great role in enhancing catalytic activities. Herein, a MnO2 [email protected] nanosheets core-shell hybrid nanostructure was successfully prepared by uniformly decorating NiO nanosheets on the one-dimensional MnO2 nanowires. The physi-chemical properties of the MnO2 and [email protected] were characterized by us...
