Boron nitride coated rhodium black for stable production of syngas

Abstract

A blanket of boron nitride grown by CVD stablizes rhodium black for syngas production in methane oxidation and avoid agglomeration of metal particle by carbon deposition.

Catalyst overcoating engineering towards high-performance electrocatalysis

“…(3) Broadening the application of the surface overcoating strategy. Besides the emerging applications in PEFCs (involving HOR, ORR, alcohol oxidation reactions) and WECs (comprising OER, HER, overall water splitting) as featured in this review article, the surface overcoating strategy also shows increasing potential for fabricating advanced nanomaterials, which are already applied in thermal-catalytic reactions, 188,[424][425][426][427][428] redox flow batteries, 429,430 metal-air batteries, 431,432 solid oxide fuel cells, [433][434][435] lithium-ion batteries or capacitors, 69,436,437 ammonia electrosynthesis, 438,439 CO 2 electrocatalytic reduction, [440][441][442] and biotechnology. 443,444 One could obtain highly dispersed fine metal nanoparticles with the aid of organic or inorganic overlayers after annealing treatment.…”

Performance Investigation of a Nickel Cermet Anode Modified with Copper, Alkaline Earth Metal Oxide, Boron, and Perovskite for Direct Methane Fuel Cell

“…Rare-earth metal oxides have been claimed to stabilize Ni particles on a catalyst support, acting as a structural promoter to improve the metal dispersion and to suppress the aggregation of Ni grains. The influence of boron on the activity and acidity of a catalyst has been known, mainly arising from better metal dispersion through structure control and metal-boron electronic interaction [27][28][29]. Nevertheless, no application of any boron promotor to a SOFC anode has been reported in the literature so far.…”

Oscillating syngas production on NiO/YSZ catalyst from methane oxidation

“…8,9 Recently, we have shown that rhodium black partially covered with hexagonal boron nitride produces syngas by methane oxidation at 650 C, following the interruption of the oxygen ow. 10 The absence of oxygen ow causes the surface oxides of the metal to reduce, thus allowing methane dissociation and the formation of a graphitic layer for syngas production. In this study, we adopted the same strategy by disturbing the oxygen ow to investigate methane oxidation on the NiO/YSZ cermet.…”
