Abstract Transition metal dichalcogenides, by virtue of their two-dimensional structures, could provide the largest active surface for reactions with minimal materials consumed, which has long been pursued in design ideal catalysts. Nevertheless, structurally perfect basal planes are typically inert; defects, such as under-coordinated atoms at surfaces or edges, can instead serve catalytically centers. Here we show a reaction probability > 90 % adsorbed methanol (CH 3 OH) on Pt sites Te...
The reactivity of layered PdTe2 toward methanol (CH3OH) decomposition was promoted by surface under-coordinated Pd (denoted as Pduc) generated removing Te with controlled Ar ion bombardment. Methanol on the Pduc sites at vacancies decomposed through competing dehydrogenation and C-O bond cleavage processes; approximately 26% converted to CHx* 17% CHxO* (* denotes adspecies; x = 2 3) major intermediates 180 K, leading a reaction probability >40% an ultimate gaseous production molecular...
Layered transition metal dichalcogenides (TMDs) are two-dimensional materials exhibiting a variety of unique features with great potential for electronic and optoelectronic applications. The performance devices fabricated mono or few-layer TMD materials, nevertheless, is significantly affected by surface defects in the materials. Recent efforts have been focused on delicate control growth conditions to reduce defect density, whereas preparation defect-free remains challenging. Here, we show...
Abstract Decomposition of adsorbed methanol (CH 3 OH) was activated on under-coordinated Pt (denoted as uc ), produced by removing Te, at layered PtTe 2 surface. Both dehydrogenation and C-O bond scission occurred, resulting in the formation intermediates CH x O* (x = 2, 3; * denotes adsorbates) 1, 2) ultimately production gaseous molecular hydrogen, methane, water formaldehyde. We observed a great reaction probability (> 90 %) sites catalytic selectivity dependent concentration....
