Therefore, the reduction of the cooling loss is very important for improving the thermal efficiency in hydrogen-combustion engines. On the other hand, the direct-injection stratified charge can suppress knocking in spark-ignition engines at near stoichiometric overall mixture conditions. Because this is...

is the world's largest photovoltaic green hydrogen production project under construction. It is also China's first 10,000-ton photovoltaic green hydrogen pilot project. Once in operation, the project could produce 20,000 tons of green hydrogen energy per year. ...
Red mud is the waste of bauxite refinement into alumina, the feedstock for aluminium production1. With about 180 million tonnes produced per year1, red mud has amassed to one of the largest environmentally hazardous waste products, with the staggering amount of 4 billion tonnes accumulated on...
The mitigation scenarios database of the Intergovernmental Panel on Climate Change’s Sixth Assessment Report is an important resource for informing policymaking on energy transitions. However, there is a large variety of models, scenario designs, a

Synthesis of 4H/fcc Noble Multimetallic Nanoribbons for Electrocatalytic Hydrogen Evolution Reaction Noble multimetallic nanomaterials, if only consisting of Au, Ag, Pt, and Pd, typically adopt the high-symmetry face-centered cubic (fcc) structure. Here for the first time, by using the 4H/fcc ...
Currently, roughly half of the hydrogen produced is used to make fertilizer and ammonia, with the balance used in petrochemical refineries or production, according to the Center on Global Energy Policy. The push for clean hydrogen is motivated both by a need to decarbonize current processes and...
of up to 99% by reduction of corresponding nitrobenzenes with hydrazine hydrate in presence of Fe5HO8·4H2O.Furthermore,the catalyst and PEG1000-DIL/toluene system could be recycled for three times without any obvious activity loss.Another noticeable advantage is that no reduction-dehalogenation ...
