Low‐Temperature in Situ Upgrading of Ultra‐Deep Heavy Oil Using Ni–Ce/MOF–OTf Superacid Catalysts to Enhance Energy Utilization and Sustainability

EcoEnergy, EarlyView.
A triflate‐functionalized Ni–Ce/MOF–OTf superacid enables low‐temperature (∼140°C) in situ upgrading of ultra‐deep heavy oil. It reduces viscosity by 92.11% in 12 h, maintains activity over cycles, and delivers 90.25% recovery with a lower carbon footprint by selective bond cleavage. ABSTRACT Ultra‐deep heavy oil is an important unconventional resource,

Liquid‐Mediated Kinetically Controlled Synthesis of Porous Carbon with Homogeneous Graphitic Networks for High‐Rate and High‐Loading Organic Supercapacitor

ENERGY &ENVIRONMENTAL MATERIALS, EarlyView.
Liquid‐mediated kinetic control reconstructs a “rigid–flexible” carbon precursor into homogeneously graphitized porous carbon. The resulting porous structure and homogeneous graphitic network accelerate ion/electron transport, enabling superior performance in high‐rate and high‐loading organic supercapacitors.

Iron‐Photocatalyzed Ligand‐to‐Metal Charge Transfer‐Driven Decarboxylative Giese‐Type Reactions Under Mild Conditions

European Journal of Organic Chemistry, EarlyView.
Iron‐photocatalyzed LMCT enables decarboxylative hydroalkylation of Michael acceptors (Giese‐type reaction) under mild conditions. Using tailored ligands and a sterically hindered very mild aniline base, diverse carboxylic acids efficiently couple with sensitive Michael acceptors, including maleimides.
