Abstract To achieve sustainable production of H 2 fuel through water splitting, low‐cost electrocatalysts for the hydrogen‐evolution reaction (HER) and oxygen‐evolution (OER) are required to replace Pt IrO catalysts. Herein, first time, we present interface engineering novel MoS /Ni 3 S heterostructures, in which abundant interfaces formed. For OER, such heterostructures show an extremely low overpotential ca. 218 mV at 10 mA cm −2 , is superior that state‐of‐the‐art OER electrocatalysts....

The electrocatalytic reduction reaction of CO2 (CO2RR) is a promising strategy to promote the global carbon balance and combat climate change. Herein, exclusive Bi-N4 sites on porous networks can be achieved through thermal decomposition bismuth-based metal-organic framework (Bi-MOF) dicyandiamide (DCD) for CO2RR. Interestingly, in situ environmental transmission electron microscopy (ETEM) analysis not only directly shows from Bi-MOF into Bi nanoparticles (NPs) but also exhibits subsequent...

The solar-driven photocatalytic reduction of CO2 (CO2 RR) into chemical fuels is a promising route to enrich energy supplies and mitigate emissions. However, low catalytic efficiency poor selectivity, especially in pure-water system, hinder the development RR owing lack effective catalysts.

Reading text from photographs is a challenging problem that has received significant amount of attention. Two key components most systems are (i) detection images and (ii) character recognition, many recent methods have been proposed to design better feature representations models for both. In this paper, we apply recently developed in machine learning -- specifically, large-scale algorithms the features automatically unlabeled data show they allow us construct highly effective classifiers...

Abstract Main‐group element indium (In) is a promising electrocatalyst which triggers CO 2 reduction to formate, while the high overpotential and low Faradaic efficiency (FE) hinder its practical application. Herein, we rationally design new In single‐atom catalyst containing exclusive isolated δ+ –N 4 atomic interface sites for electroreduction formate with efficiency. This exhibits an extremely large turnover frequency (TOF) up 12500 h −1 at −0.95 V versus reversible hydrogen electrode...

Developing industrial-grade electroreduction of CO2 to produce formate (HCOO–)/formic acid (HCOOH) depends on highly active electrocatalysts. However, structural changes due the inevitable self-reduction catalysts result in severe long-term stability issues at current density.
