WebAbstract: Layered graphitic carbon nitride (g-C 3 N 4) is a typical polymeric semiconductor with an sp 2 π-conjugated system having great potential in energy conversion, environmental purification, materials science, etc., owing to its unique physicochemical and electrical properties.However, bulk g-C 3 N 4 obtained by calcination suffers from a low specific …
Webmembrane system, the gas flows inside the hollow fibers and the amine solvent flows exterior to hollow fibers. PEEK membranes are super-hydrophobic and nano-porous, that is, the solvent will not wet the membrane pores, and the nano -sized pores will remain gas filled. The result is extremely low resistance in the open pores to gas mass transfer. someone who gets mad easilyWebMechanically robust, hollow carbon nanotube composite spheres that are permeable to large chemical species were prepared by a layer-by-layer assembly and templating … small cake for 2 personWeb已主持包括 国家自然科学基金项目 以及其它国家、部、省、企业等研究课题30余项。. 长期从事纳米材料的设计合成及电化学性能、电化学储能材料、纳米复合材料及表面技术等研究工作。. 获教育部自然科学二等奖一项（第一完成人），主持的项目“化学气相 ... someone who ghosted youWebFeb 18, 2016 · Three-dimensional porous hollow fibre copper electrodes for efficient and high-rate electrochemical carbon dioxide reduction.
