| الوصف: | 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; (${\rm{Na}}{{\rm{H}}_2}{\rm{P}}{{\rm{O}}_2}$·${{\rm{H}}_2}{\rm{O}}$)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303 K、反应混合液为1; mol/L FA和3 mol/L甲酸钠(SF)的条件下,前1 h反应的平均转化频率(TOF)达到798; ${{\rm{h}}^1}$,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 ${{\rm{h}}^1}$ 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. ; 国家重点基础研究发展计划(973计划)项目; 福建省自然科学基金 |
