In this work,the influence of CO2 on the structural variation and catalytic performance of Na2WO4/Mn/Si O2 for oxidative coupling of methane to ethylene was inv
SAPO-34 molecular sieves were synthesized by the addition of β-cyclodextrin(β-CD) as crystal growth inhibitor using metakaolin as silicon and aluminum sources
The membrane-electrodes assembly(MEA) is the core of the Polymer Electrolyte Fuel Cell(PEFC). It consists of a membrane, catalytic(CL) and gas diffusion layers(
