Hierarchical porous g-C₃N₄ nanosheets are prepared from melamine using NH₄Cl as dynamic gas templates to anchor the ultrafine Ru nanoparticles (NPs) with a facile adsorption-in situ reduction strategy. The results reveal that 1: 3 is the optimal mass ratio for melamine to NH₄Cl and the Ru NPs are evenly dispersed in the porous network of g-C₃N₄ in the corresponding catalysts. Remarkably, the porous catalysts exhibit superior catalytic activity and satisfactory recyclability for ammonia borane (NH₃-BH₃, AB) hydrolysis. The corresponding turnover frequency is as high as 122.2 × 10³ ${\text{mL}}_{{\text{H}}_2}\text{·}{\text{g}}_{\text{Ru}}^{\text{-1}}\text{·}{\text{min}}^{\text{-1}}$ and the apparent activation energy (35.6 kJ mol^-1) is competitive. AB hydrolysis is of 1.17-order and near zero-order with respect to the Ru and AB concentrations, respectively. The results demonstrate that the Ru/g-C₃N₄ catalysts are promising in developing an alternative clean and environmentally friendly energy carrier from the hydrogen storage materials.

分层多孔gC ₃ N ₄纳米片由三聚氰胺制成，使用NH ₄ Cl作为动态气体模板，以易于吸附的原位还原策略固定超细Ru纳米颗粒（NPs）。结果表明，三聚氰胺与NH ₄ Cl的最佳质量比为1：3 ，Ru NPs均匀地分散在相应催化剂中的gC ₃ N ₄的多孔网络中。显着地，该多孔催化剂对于氨硼烷（NH ₃ -BH ₃，AB）水解显示出优异的催化活性和令人满意的再循环能力。相应的周转频率高达122.2×10 ³ ${\text{毫升}}_{{\text{H}}_2}\text{·}{\text{G}}_{\text{茹}}^{\text{-1}}\text{·}{\text{分}}^{\text{-1}}$表观活化能（35.6 kJ mol ^-1）具有竞争力。相对于Ru和AB浓度，AB水解分别为1.17级和接近零级。结果表明，Ru / gC ₃ N ₄催化剂有望从储氢材料开发出替代的清洁且环保的能量载体。
