Highly efficient and stable Ru-free catalyst for hydrogen generation from ammonia

Green Car Congress

Although the thermocatalytic ammonia decomposition reaction (ADR) is an effective way to obtain clean hydrogen, it relies on the use of expensive and rare ruthenium (Ru)-based catalysts, making it not sustainable or economically feasible. A complete ammonia conversion to hydrogen was achieved at an economically feasible 450 ?C

Three-part catalyst study advances conversion of CO2 to ethanol

Green Car Congress

An international collaboration of scientists has taken a significant step toward the realization of a nearly “green” zero-net-carbon technology that can efficiently convert CO 2 and hydrogen into ethanol. None of the three components examined in the study is able to individually catalyze the CO 2 -to-ethanol conversion, nor can they in pairs.

Researchers develop earth-abundant photocatalyst for conversion of ammonia into hydrogen

Green Car Congress

and Princeton University’s Andlinger Center for Energy and the Environment have created a scalable photocatalyst that can convert ammonia into hydrogen fuel. This result demonstrates the potential for highly efficient, electrically driven production of hydrogen from an ammonia carrier with earth-abundant transition metals.

Cobalt-doped graphdiyne catalyst for catalytically decomposing ammonia to hydrogen

Green Car Congress

In a paper in the journal Fuel , the researchers report that the Co-doped graphdiyne catalyst achieved nearly complete decomposition of ammonia at 550 ˚C, and the conversion rate remained stable over 18 h of continuous reaction. Ammonia is by its nature a high-density hydrogen carrier. —Liu et al.

Researchers use chemical looping process to produce hydrogen from hydrogen sulfide gas

Green Car Congress

Researchers at The Ohio State University have used a chemical looping process to produce hydrogen from hydrogen sulfide gas—commonly called “sewer gas”. Hydrogen sulfide is emitted from manure piles and sewer pipes and is a key byproduct of industrial activities including refining oil and gas, producing paper and mining.
