AI Article Synopsis

  • The formation of an additional phase, (CHNH)MnCl, occurs when the concentration of Mn dopant increases, hindering the creation of Mn-doped CHNHPbCl nanocrystals (NCs).
  • By altering the order in which MnCl is added during the crystal growth process, this new approach can help prevent the emergence of the unwanted impurity phase.
  • This method enhances the potential for successfully synthesizing Mn-doped CHNHPbCl NCs without contamination.

Article Abstract

The additional (CHNH)MnCl phase was observed upon increasing the Mn dopant concentration, preventing the formation of Mn-doped CHNHPbCl NCs. We introduce an approach to avoid the formation of an impurity phase by switching the sequence for the addition of MnCl in the crystal growth process.

ConspectusThe discovery of reversible hydrogenation using metal-free phosphoborate species in 2006 marked the official advent of frustrated Lewis pair (FLP) chemistry. This breakthrough revolutionized homogeneous catalysis approaches and paved the way for innovative catalytic strategies. The unique reactivity of FLPs is attributed to the Lewis base (LB) and Lewis acid (LA) sites either in spatial separation or in equilibrium, which actively react with molecules.

Recently, lithium-sulfur batteries have captivated those in the energy storage industry due to the low cost and high theoretical capacity of the sulfur cathode (1675 mA h g). However, to enhance the practical usability of Li-S batteries, it is crucial to address issues such as the insulating nature of sulfur cathodes and the high solubility of lithium polysulfides (LiPS, LiS , 4 ≤ ≤ 8) that cause poor active sulfur utilization. Designing innovative sulfur hosts can effectively overcome sulfur bottlenecks and achieve stable Li-sulfur batteries.

Gold nanoclusters (Au NCs) protected by molecular ligands represent a new class of second-generation near-infrared (NIR-II) luminescent materials that have been widely studied. However, the photoluminescence efficiencies of most NIR-II emitting Au NCs in aqueous solution are generally lower than 0.2%, and to fully exploit the advantages of AuNCs in the NIR-II region, improving their photoluminescence efficiency has become an urgent need.

Dual atomic nanozymes (DAzymes) are promising for applications in the field of tumor catalytic therapy. Here, integrating with ultrasmall FeC nanoclusters, asymmetric coordination featuring Janus Zn-Fe dual-atom sites with an ON-Fe-Zn-N moiety embedded in a carbon vacancy-engineered hollow nanobox (Janus ZnFe DAs-FeC) was elaborately developed. Theoretical calculation revealed that the synergistic effects of Zn centers acting as both adsorption and active sites, oxygen-heteroatom doping, carbon vacancy, and FeC nanoclusters jointly downshifted the d-band center of Fe 3d orbitals, optimizing the desorption behaviors of intermediates *OH, thereby significantly promoting catalytic activity.
