摘要
甲酸(FA)分解制氢是解决能源问题的有效途径,而开发一类高效、稳定、廉价的催化剂是FA分解制氢在未来得到广泛应用的关键.联合使用一水合次亚磷酸钠(NaH2PO2·H2O)和二甲胺硼烷(DMAB)作为还原剂,成功制备了一类B、P共掺杂的Pd基催化剂,其对FA分解制氢具有较高的活性和选择性.在303K、反应混合液为1 mol/L FA和3mol/L甲酸钠(SF)的条件下,前1h反应的平均转化频率(TOF)达到798h-1,通过气相色谱检测发现分解后的气体产物中CO的体积分数小于0.01%,保证了分解得到氢气的清洁.
Dehydrogenation via formic acid decomposition is an effective way to solve energy problem,and the development of a class of highly efficient,stable and cheap catalyst is the key to extensive applications of formic acid dehydrogenation in the future.In this paper,a new kind of double doped Pd-based catalyst（Pd-B-P/C）were successfully prepared by using hydrated sodium hypophosphite and dimethylamine borane（DMAB）as reducing agent,which displayed high activity and selectivity for decomposition of formic acid.Under optional reaction conditions：303 K,1 mol/L formic acid and 3 mol/L sodium formate,the turn-over frequency（TOF）of formic acid decomposition over the Pd-B-P/C catalyst reached 798 h^-1 in the first 1 hour.The gas products from decomposition of the formic acid were measured by gas chromatography and found that the fractional volume of CO was less than 0.01%,which ensured the decomposed hydrogen clean and pure.
