Abstract
Fossil-derived diesel raises sustainability and air-quality concerns, motivating biomass-based alternatives; however, current biodiesel routes suffer from food-fuel competition, poor fuel properties, and energy-intensive upgrading. Electrocatalytic C─C coupling of biomass molecules followed by hydrodeoxygenation (HDO) offers a cleaner pathway, yet has been limited to dimer formation. Here, we successfully resolved this longstanding bottleneck through construction of Pd1Cu single-atom alloy electrocatalyst, a trimer of 5-hydroxymethylfurfural is obtained with 44.7% selectivity. The combined oligomer (dimer and trimer) selectivity reaches 95.0% with 93.2% Faradaic efficiency, production rate achieves a record high of ∼50 g gcat -1 h-1. Subsequent HDO converts the oligomers into heteroatom-free n-dodecane and n-octadecane diesel blendstocks. Operando spectroscopy reveals a surface-confined ketyl-radical pathway in which isolated Pd atoms regulate hydrogen-atom supply and substrate adsorption, favoring C─C coupling over hydrogenation. This work establishes an electricity-driven route for controlled carbon-chain growth from biomass platforms.
Electrochemical green ammonia (NH3) production using renewable electricity is sustainable but suffers from selectivity-activity-stability trade-off under industrial conditions. Here we report an atomic interface engineering strategy enabling in-situ assembly and coupling of hexaethynylbenzenes on molybdenum-copper oxid...
Electrochemical glycerol oxidation offers a sustainable pathway for valorizing biodiesel-derived glycerol while lowering the energy demand of hydrogen production. However, Co-based catalysts are often limited by inefficient coupling between the electrochemical generation and chemical consumption of oxidized Co species....

Branched C8-C16 alkanes are highly desirable sustainable aviation fuel (SAF) components, as they confer low freezing points and favorable combustion properties. Currently, these alkanes are produced predominantly via the hydroprocessed esters and fatty acids (HEFA) pathway, which requires harsh hydrogenation and hydroi...

Biomass is an abundant renewable carbon resource for the sustainable production of fuels and value-added chemicals. Electrocatalytic hydrogenation (ECH) provides a mild and attractive route for upgrading biomass-derived molecules without the need for externally supplied high-pressure H2. However, the structural complex...
Electrocatalytic hydrogenation (e -H) provides a sustainable route for converting unsaturated organic substrates under mild conditions using renewable electricity as the driving force. Here, we report an MOF-derived cobalt catalyst for the e -H of acetone and pyridine. A new two-dimensional cobalt metal-organic framewo...

The electrochemical reduction of nitrate (NO3 -) offers a green and sustainable approach for treating nitrogen-containing wastewater and is regarded as a promising alternative to the energy-intensive Haber-Bosch process. However, this reaction entails multielectron transfer and complex reaction pathways, and its effici...
