Supported rhodium nanoparticles (NPs) are well-known for catalyzing methanation in CO2 hydrogenation. Now we demonstrate that the selectivity this process can be optimized CO production by choice of molecular sieve crystals as supports. The NPs enveloped within with controlled nanopore environments allow tuning catalytic to minimize and favor reverse water–gas shift reaction. Pure silica MFI (S-1)-fixed exhibited maximized at high conversions, whereas aluminosilicate zeolite-supported...
Isolating and stabilizing boron Oxidative dehydrogenation of propane can produce propene from shale gas help to replace petroleum as a feedstock. Boron-based catalysts have high selectivity propene, but the water by-product deactivate catalyst by hydrolyzing boron. Zhou et al. synthesized boron-doped silicate zeolites containing isolated sites that were stable against hydrolysis. The could achieve one-pass conversions up ∼44% with selectivities for >80% ethene. They observed no...
