摘要： High surface area 3D mesoporous carbon nanocomposites can be derived from Zn dust and PET bottle mixed waste with a high surface area. Simultaneous transformation of Zn metal into ZnO nanoparticles and PET bottle waste to porous carbon materials can be achieved by thermal treatment at preferably 600 to 800° C., and reaction times of from 15 to 60 minutes, after optionally de-aerating the reaction mixtures with N2 gas. The waste-based carbon materials can have surface areas of 650 to 725 m2/g, e.g., 684.5 m2/g and pore size distributions of 12 to 18 nm. The carbon materials may have 3D porous dense layers with a gradient pore structure, which may have enhanced photocatalytic performance for degrading, e.g., organic dyes, such as methylene blue and malachite green. Sustainable methods make ZnO-mesoporous carbon materials from waste for applications including photocatalysis, upcycling mixed waste materials.

摘要： A composite is synthesized by pyrolysis of a mixture of tannin and melamine. The synthesis process comprises dissolving the tannin and the melamine in water to form a homogeneous solution; evaporating the solution to yield a dry solid; and subjecting powders of the dry solid to a heat treatment at a temperature for a duration of time effective to produce the composite.

摘要： The present disclosure provides a synthesis method of a g-C3N4/C composite material based on a hollyhock stalk, including the following steps: (1) pretreatment of hollyhock stalks; and (2) fabrication of the g-C3N4/C composite material. In this method, with the hollyhock stalk as a carbon skeleton, g-C3N4 is spread on a template surface to form a laminated layer, and a composite system with a special structure is constructed. Compared with pure phase g-C3N4, the composite material substantially increases specific surface area and has a clear interface; the carbon skeleton not only functions as a rigid support, but also increases the electron transfer efficiency of the composite material, thereby improving the separation efficiency of photogenerated carriers and the utilization rate of visible light. Raw materials used in the method are inexpensive and environmentally friendly, which can be used for industrial production and bulk production of eco-friendly materials for harnessing environmental organic pollutants.

摘要： A hydrodemetallization (HDM) catalyst includes an alumina and carbon extrudate support having a weight ratio of about 1:1 alumina to carbon and bimodal type pore size distribution, i.e., both meso-porosity and macro-porosity. The support can be impregnated with at least one hydrogenation active metal and, optionally, at least one promoter metal from the transition metals of Groups 6, 8, 9, and 10 of the Periodic Table. The hydrogenation active metal can be, for example, Mo, W, and Fe. The promoter metal can be, for example, Co, Ni, and Fe. The catalyst may further include ethylene diamine tetra acetic acid (EDTA).

摘要： A method of making solid acid catalysts includes the step of sulfonating waste tire pieces in a first sulfonation step. The sulfonated waste tire pieces are pyrolyzed to produce carbon composite pieces having a pore size less than 10 nm. The carbon composite pieces are then ground to produce carbon composite powders having a size less than 50 μm. The carbon composite particles are sulfonated in a second sulfonation step to produce sulfonated solid acid catalysts. A method of making biofuels and solid acid catalysts are also disclosed.

摘要： Disclosed are methods for making monolithic carbon materials as single bodies containing networks of pores in the mesopore and macropores that incorporate nanoparticles of various metals and metal oxides. The disclosed methods have the advantage that such single bodies can be made by mixing the carbon precursors and metal salts together in a single pot followed by appropriate processing. The materials produced are particularly suitable for use as heterogeneous catalysts, particularly in fixed bed and monolithic reactors.
