Surface Organometallic Chemistry for Single-site Catalysis and Single-atom Catalysis
Although driven by different research interests, single-site catalysts and single-atom catalysts are both believed to be model systems bridging homogeneous and heterogeneous catalysis. The two concepts are sim...

Open AccessAtomic overlayer of permeable microporous cuprous oxide on palladium promotes hydrogenation catalysis
The interfacial sites of metal-support interface have been considered to be limited to the atomic region of metal/support perimeter, despite their high importance in catalysis. By using single-crystal surface ...

Open AccessA decomposition formula for the wall heat flux of a compressible boundary layer
Understanding the generation mechanism of the heat flux is essential for the design of hypersonic vehicles. We proposed a novel formula to decompose the heat flux coefficient into the contributions of differen...

Atomically dispersed iridium on MgO(111) nanosheets catalyses benzene–ethylene coupling towards styrene
Single-atom catalysis is recognized as a frontier of heterogeneous catalysis for its efficient utilization of metals and the possibility to engender unusual reactivity. Yet, despite the observation of single a...

A New Hybrid WENO Scheme on a Four-Point Stencil for Euler Equations
To enhance the performance of the third-order weighted essentially non-oscillatory (WENO) scheme on the four-point stencil, a new hybrid central-type scheme is proposed in this paper. Developments are conducte...

Facet engineering accelerates spillover hydrogenation on highly diluted metal nanocatalysts
Hydrogen spillover is a well-known phenomenon in heterogeneous catalysis; it involves H2 cleavage on an active metal followed by the migration of dissociated H species over an ‘inert’ support1–5. Although catalyt...

Alkali ions secure hydrides for catalytic hydrogenation
Catalytic hydrogenation is one of the backbones of the chemical industry. Controlling the reaction behaviour of the activated hydrogen species over oxide-supported metal catalysts is essential. Aside from the ...

Open AccessInterfacing with silica boosts the catalysis of copper
Metal-support interaction is one of the most important parameters in controlling the catalysis of supported metal catalysts. Silica, a widely used oxide support, has been rarely reported as an effective suppor...

Air-promoted selective hydrogenation of phenol to cyclohexanone at low temperature over Pd-based nanocatalysts
Attaining high activity with high selectivity at low temperature is challenging in the selective hydrogenation of phenol to cyclohexanone due to its high activation energy (Ea, 55–70 kJ/mol). Here we report a sim...

A Fourth-Order Symmetric WENO Scheme with Improved Performance by New Linear and Nonlinear Optimizations
A fourth-order, symmetric, weighted essentially non-oscillatory scheme is proposed with improved linear and nonlinear properties. In order to improve its linear property as the dispersion and dissipation relat...

New Methods for Resolution Improvement in Simulations on Subtle Structures Generated by Shock Waves
Since the first introduction of the weighted essentially non-oscillatory (WENO) scheme in [1], the efficient implementation in [2] made the algorithm applicable to realistic problems. Despite the success, some...
