Synthesis of Porous α-Fe2O3 Nanorods and Deposition of Very Small Gold Particles in the Pores for Catalytic Oxidation of CO FeO(OH) nanorods were prepared by a mild hydrothermal synthesis using tetraethylammonium hydroxide (TEAOH) as the structure director. The as-prepared FeO(O... Z Zhong,...
采用自制SO42-/ZrO2固体酸催化剂,在氢还原体系中对碱木质素进行活化,以化学法对活化前、后碱木质素的官能团含量进行定量分析,利用 DPP H自由基清除率、超氧阴离子自由基清除能力和还原力对碱木质素的抗氧化性能进行评价.结果表明,活化后碱木质素的总羟基和酚羟基含量分别达到9.39%和3.32%,较反应前提高55.98%和...

The effect of acidity in the combustion of CVOCs, such as promoting the adsorption of CVOCs [7], [9] and the removal of Cl species produced during the reaction, was understood to some extent [5], [11], [18]. It was found that in dichloromethane (DCM) oxidation over Pt/Al2O3 [...
