Elucidating the Role of Support Structure and Acid–Base Properties in Rh-Catalyzed CO2 Conversion via the Reverse Water Gas Shift Reaction

Abstract The reverse water–gas shift reaction provides a viable pathway for CO2 valorization into CO, a key intermediate for the sustainable synthesis of fuels and chemicals. In this study, Rh catalysts supported on silica and aluminosilicate materials, including SiO2, MCM-41, Si...

Nanowire-Threaded NiZn Layered Double Hydroxide Nanocage Heterostructures for High-Performance Supercapacitors

Abstract Layered double hydroxides (LDHs), featuring tunable compositions and unique layered structures, have been widely investigated as electrode materials for supercapacitors. However, their electrochemical performance is often limited by intrinsically low electrical conductiv...

Electric vehicle deployment in India: implications for critical material demand and the role of recycling through 2060

The rapid expansion of India’s on-road vehicle fleet creates opportunities and challenges for future energy systems, particularly for critical material requirements of electric vehicles (EVs). This study develops a bottom-up model of India’s passenger and commercial vehicle fleet...

Biodiesel soot incandescence and NO emission studied in an optical engine

High-speed imaging and thermodynamical characterization are applied to an optically accessible, heavy-duty diesel engine in order to compare soot incandescence and NO emission behaviour of four bioderived fuels: rapeseed-methylester, Jatropha oil (pure), Jatropha-methylester and...

Near-Atomic Indium Catalysts Enable Cost-Efficient High-Pressure Reverse Water–Gas Shift

Abstract The reverse water–gas shift (RWGS) reaction is a pivotal step for converting CO2 into value-added chemical intermediates, yet its implementation under industrially relevant high-pressure conditions remains limited by catalyst deactivation, insufficient productivity, and...
