In this work, the gaseous species (AlxOy) of metal Al has been thermodynamically analyzed and discussed under air embedded in coke breeze. The resin bonded Al-Al2O3-ZrO2 refractories are prepared to investigate the effect of metal Al and AlxOy(g) on phase composition and micro-structure at high temperatures under air embedded in coke breeze. The re...

This study aims to investigate the potential of zeolitic based catalysts for biodiesel production from waste sunflower vegetable oil. The zeolite-based catalyst was prepared by two impregnation steps. The obtained catalyst was examined for the transesterification reaction. The effect of operating variables and the synergetic effects between those v...
Controlled chemical functionalization of graphite's outer surface layers into photocatalytically oxidized graphite (POG) is reported. POG can be easily prepared via a UV-driven process using titanium dioxide photocatalyst in molecular oxygen and water vapor at relatively low temperature. The photo-oxidation offers a mild and highly controllable pro...
The non-toxic biologic material of expanded corn starch (ECS)-supported nitric acid (ECS-HNO3 and ECS-NH2-HNO3) has been prepared via simple procedures. Both the materials are used as heterogeneous catalysts for the selective aerobic oxidation of 5-hydroxymethylfurfural (HMF) to 2,5-diformylfuran (DFF) with an up to 98% yield in gamma-butyrolactone...
WO3 photoanodes offer rare stability in acidic media, but are limited by their selectivity for oxygen evolution over parasitic side reactions, when employed in photoelectrochemical (PEC) water splitting. Herein, this is remedied via the modification of nanostructured WO3 photoanodes with surface decorated PdO as an oxygen evolution co-catalyst (OEC...
The direct synthesis of methyl acrylate (MA) from methyl acetate and trioxane at 350-380 degrees C is regarded as a supplementary route for the industrial propylene oxidation process; however, it suffers from rapid catalyst deactivation. Herein, a novel ionic liquid catalyzed mild liquid-phase system was developed for the direct synthesis of MA fro...

The electrochemical oxygen evolution reaction (OER) and oxygen reduction reaction (ORR) are two critical processes for energy conversion technologies, including water electrolysis, fuel cells, and metal-air batteries. For technological implementation, both reactions require highly active and stable electrocatalysts. Here, we report the simultaneous...
Nowadays, it is necessary and challenging to prepare monolithic catalysts, which are ready for use, preventing the tedious and complicated integration procedure of the powder materials onto a porous substrate. Herein, Cu2O nanoparticles are successfully synthesized onto a porous Cu foam in one pot via the surface oxidation, coordination and precipi...
