Bimetallic NiCe/Lay catalysts facilitated co-pyrolysis of oleic acid and methanol for efficiently preparing anaerobic hydrocarbon fuels

Abstract

Bimetallic NiCe/Lay catalysts were prepared and achieved a conversion rate of oleic acid of 100% and a hydrocarbon selectivity of 92.77%.

Regulable surface hydroxyl group content in disperse ultrafine amorphous SiO2 nanoparticles

“…As the surface silanol group content in the amorphous SiO 2 NPs can be tuned in a broad range by controlling calcination temperature and rehydroxylation treatment conditions, their adsorption capacity can also be varied in a broad range, which enables the applications of the amorphous SiO 2 NPs with different surface silanol group contents for scenes of different adsorption capacities required 60–63 …”

Novel electrode material based on coral-like cerium orthoferrite (CeFeO3) for efficient alkaline water splitting

“…1,6,7 While cerium orthoferrite (CeFeO 3 ) remains the least explored among these materials, incorporating cerium into the composition of an electrocatalyst or utilizing cerium ( iv ) oxide as a substrate has demonstrated a propensity to augment the reactivity of catalytic active sires in the HER process. 8,9 Several methods are available for synthesizing REE orthoferrites, including sol–gel synthesis, high-temperature solid-state synthesis, hydrothermal synthesis, calcination of polymeric precursors, and solution combustion synthesis. However, due to the inherent instability of Ce 3+ compounds at high temperatures in the presence of air, they tend to oxidize to Ce 4+ and form CeO 2 , thereby disrupting the single-phase structure of CeFeO 3 .…”

Graphene Aerogels Embedded with Boron Nitride Nanoparticles for Solar Energy Storage and Flame-Retardant Materials

“…In order to cope with the depletion of traditional fossil energy and environmental challenges, researchers are committed to finding new stable alternative energy. − Besides hydrogen, fuel cells and electrochemical energy like supercapacitors or batteries, − and thermoelectric energy, , new energy sources with environmental protection and recyclable characteristics, such as solar energy, wind energy, tidal energy, and geothermal energy, have been significantly developed after years of research . However, the imbalance between the energy supply and demand in time and space limits their wide application.…”
