Electrocatalytic N2 reduction to NH3 is an attractive method for artificial fixation at ambient conditions. Herein, we demonstrate that Fe-NC materials could be efficient electrochemical reaction (NRR) using iron phthalocyanine (FePc) with a well-defined FeN4 configuration as model catalyst. By uniformly loading FePc molecules on porous carbon, it exhibits high electrocatalytic activity NRR yield rate of 137.95 μg h–1 mg–1FePc low potential −0.3 V (vs RHE). Importantly, by making comparisons...
Abstract Green and scalable syntheses of highly dispersed supported metal nanocatalysts (SMNCs) are significant importance for heterogeneous catalysis in industry. In order to achieve nanosized SMNCs prevent nanoparticles (NPs) from aggregation, the traditional liquid commonly require organic capping agents low loading, which unfavorable practical production SMNCs.

Abstract Electroless deposition via a spontaneous redox reaction between the metal precursor and support is believed to be promising approach for syntheses of supported nanoparticles (SMNPs). However, its widespread applications are significantly prohibited by low reductivity high cost support. To overcome these shortcomings, porous carbon (PC) herein developed as matrix electroless NPs. Benefiting from abundant oxygen‐based surface functional groups, PC shows stronger reducibility (low...

Herein, uniformly dispersed and size-controllable iridium (Ir) nanoparticles (NPs) were prepared using a nitrogen-functionalized carbon as the support (Ir/CN). We found that nitrogen functionalization can simultaneously modulate size of Ir NPs to substantially enhance catalytically active sites adjust electronic structure Ir, thereby promoting electrocatalytic activity splitting. Consequently,...

This paper is concerned with the multi-dimensional compressible Euler equations time-dependent damping of form $-\frac{\mu}{(1+t)^\lambda}\rho\boldsymbol u$ in $\mathbb R^n$, where $n\ge2$, $\mu>0$, and $\lambda\in[0,1)$. When $\lambda>0$ bigger, effect time-asymptotically gets weaker, which called under-damping. We show optimal decay estimates solutions such that $\|\partial_x^\alpha (\rho-1)\|_{L^2(\mathbb R^n)}\approx (1+t)^{-\frac{1+\lambda}{2}(\frac{n}{2}+|\alpha|)}$, \boldsymbol...
