Abstract Single-atom catalysts offering intriguing activity and selectivity are subject of intense investigation. Understanding the nature single-atom active site its dynamics under working state crucial to improving their catalytic performances. Here, we identify at atomic level a general evolution single atom into near-free electrocatalytic hydrogen condition, via operando synchrotron X-ray absorption spectroscopy. We uncover that Pt tends dynamically release from nitrogen-carbon...
Controlling the chemical environments of active metal atom including both coordination number (CN) and local composition (LC) is vital to achieve stable single-atom catalysts (SACs), but remains challenging. Here we synthesized a series supported Pt1 SACs by depositing Pt atoms onto pretuned anchoring sites on nitrogen-doped carbon using atomic layer deposition. In hydrogenation para-chloronitrobenzene, SAC with higher CN about four less pyridinic nitrogen (Npyri) content exhibits remarkably...
Regulation of the atom-atom interspaces dual-atom catalysts is essential to optimize synergy achieve high activity but remains challenging. Herein, we report an effective strategy regulate Pt1 -Ni1 interspace Ni1 dimers and +Ni1 heteronuclear dual-single-atom (HDSACs) by tailoring steric hindrance between metal precursors during synthesis. Spectroscopic characterization reveals obvious electron transfers in oxo not HDSAC. In hydrolysis ammonia borane (AB), H2 formation rates show inverse...
Supported low-nuclearity cluster catalysts (LNCCs, for example, the number of metal atoms is 2 ≤ n 10), between single and nanoclusters in size, possess not only maximum atom efficiency but also highly tunable structures, including nuclearity, composition, local chemical environment, quantum electronic holding great promise advanced catalysis terms high activity, selectivity, stability at low cost. In contrast to single-atom catalysts, LNCCs can provide multiple adsorption sites initiate...
Nitric oxide (NO) not only plays a vital role in series of physiological processes but also has great potential for therapeutic applications. One the existing challenges using NO as gas is inconvenience gaseous storage, and thus, it importance to develop NO-releasing vehicle platforms. Although variety polymer-based nanoparticles have been constructed, majority systems are limited spherical morphologies. Here we present preparation biodegradable amphiphilic block copolymers containing...
