Boron has been explored as p-block catalysts for nitrogen reduction reaction (NRR) by density functional theory. Unlike transition metals, on which the active centers need empty d orbitals to accept lone-pair electrons of molecule, sp3 hybrid orbital boron atom can form B-to-N π-back bonding. This results in population N-N π* and concomitant decrease bond order. We demonstrate that catalytic activity is highly correlated with degree charge transfer between substrate. Among 21...

Abstract Water molecules, which act as both solvent and reactant, play critical roles in photocatalytic reactions for methanol conversion. However, the influence of water on adsorption desorption liquid products, are two essential steps that control performance photocatalysis, has been well under‐explored. Herein, we reveal role heterogeneous processes conversion platinized carbon nitride (Pt/C 3 N 4 ) model photocatalyst. In situ spectroscopy techniques, isotope effects, computational...

Carbon composite monoliths were prepared from a commercial phenolic resin mixed with just 1 wt% of carbon nanotubes (CNTs) followed by carbonization and physical activation CO2. The products possess hierarchical macroporous–microporous structure superior CO2 adsorption properties. In particular, they show the top-ranked capacity (52 mg per g adsorbent at 25 °C 114 mmHg) under low partial pressures, which is more relevance for flue gas applications. This matches or exceeds those carbons...
Current metal-free catalysts for hydrogen evolution reaction (HER) are mainly carbon-based. In this work, HER catalytic activity on two-dimensional (2D) boron sheets (α and β12) explored using periodic density functional theory. Using the binding free energy of H (ΔGH*) as descriptor, we found that both α β12 present superior activity, with ΔGH* being close to zero. It is expected 2D would be a promising catalyst in electrolysis water may offer novel thoughts design new other reactions.

Recently, there have been significant advancements in large language models (LLMs), particularly focused on the English language. These enabled these LLMs to understand and execute complex instructions with unprecedented accuracy fluency. However, despite advancements, remains a noticeable gap development of Chinese instruction tuning. The unique linguistic features cultural depth pose challenges for tuning tasks. Existing datasets are either derived from English-centric or ill-suited...
