In this study, grinded apricot kernel shell (GAKS) biobased waste was used for the first time as a cost-effective, efficient, green and metal-free catalyst for hydrogen generation from the hydrolysis reaction of sodium borohydride (NaBH₄). For the hydrogen production by NaBH₄ hydrolysis reaction, GAKS was treated with various acids (HCl, HNO₃, CH₃COOH, H₃PO₄), salt (ZnCl₂) and base (KOH). As a result, the phosphoric acid (H₃PO₄) demonstrated better catalytic activity than other chemical agents. The hydrolysis of NaBH₄ with the GAKS-catalyst (GAKS_cat) was studied depending on different parameters such as acid concentration, furnace burning temperature and time, catalyst amount, NaBH₄ concentration and hydrolysis reaction temperature. The obtained GAKS_cat was characterized by ICP-MS, elemental analysis, TGA, XRD, FT-IR, Boehm, TEM and SEM analyses and was evaluated for its catalytic activity in the hydrogen production from the hydrolysis reaction of NaBH₄. According to the results, the optimal H₃PO₄ percentage was found as 15%. The maximum hydrogen generation rate from the hydrolysis of NaBH₄ with the GAKS_cat was calculated as 20,199 mL min⁻¹ g_cat⁻¹. As a result, it can be said that GAKS treated with 15% H₃PO₄ as a catalyst for hydrogen production is an effective alternative due to its high hydrogen production rate.

在这项研究中，首次使用磨碎的杏壳（GAKS）生物基废物作为经济高效，高效，绿色和不含金属的催化剂，用于硼氢化钠（NaBH ₄）的水解反应中产生氢气。为了通过NaBH ₄水解反应产生氢，将GAKS用各种酸（HCl，HNO ₃，CH ₃ COOH，H ₃ PO ₄），盐（ZnCl ₂）和碱（KOH）处理。结果，磷酸（H ₃ PO ₄）显示出比其他化学试剂更好的催化活性。用GAKS催化剂（GAKS _cat水解NaBH ₄）是根据不同的参数进行研究的，例如酸浓度，炉子燃烧温度和时间，催化剂用量，NaBH ₄浓度和水解反应温度。通过ICP-MS，元素分析，TGA，XRD，FT-IR，Boehm，TEM和SEM分析对所得的GAKS_猫进行表征，并评价其对NaBH ₄水解反应制氢的催化活性。根据该结果，发现最佳的H ₃ PO ₄百分比为15％。通过GAKS _cat水解NaBH ₄产生的最大氢生成速率为20,199 mL min ^-1 g _cat ^-1。结果，可以说用15％的H ₃ PO ₄作为制氢催化剂处理的GAKS由于其高的制氢率是有效的选择。
