It has long been rec\u00adog\u00adnized that the reac\u00adtion rates of the hydro\u00adgen oxi\u00adda\u00adtion and hydro\u00adgen evo\u00adlu\u00adtion reac\u00adtions (HOR and HER) are slow\u00ader in basic than acidic elec\u00adtrolytes, even though the sur\u00adface inter\u00adme\u00addi\u00adate of adsorbed hydro\u00adgen is inde\u00adpen\u00addent of solu\u00adtion pH. Under\u00adstand\u00ading the root of this obser\u00adva\u00adtion is crit\u00adi\u00adcal to design\u00ading cat\u00ada\u00adlysts for a mul\u00adti\u00adtude of elec\u00adtro\u00adchem\u00adi\u00adcal reac\u00adtions with rel\u00ade\u00advance to ener\u00adgy con\u00adver\u00adsion and stor\u00adage. In this work, we under\u00adtake both applied and fun\u00adda\u00admen\u00adtal efforts to under\u00adstand the mech\u00ada\u00adnisms and devel\u00adop low-cost, active cat\u00ada\u00adlysts for the hydro\u00adgen reac\u00adtions in base.<\/p>\n In the first part of the talk, we uti\u00adlize a the\u00ado\u00adry-guid\u00aded approach to devel\u00adop nick\u00adel-sil\u00adver cat\u00ada\u00adlysts for alka\u00adline hydro\u00adgen evo\u00adlu\u00adtion and oxi\u00adda\u00adtion.

Our mea\u00adsure\u00adments show that the alloy is indeed more active for hydro\u00adgen evo\u00adlu\u00adtion than pure nick\u00adel. In the sec\u00adond part of the talk, we exam\u00adine specif\u00adi\u00adcal\u00adly the hypoth\u00ade\u00adsis that water ori\u00aden\u00adta\u00adtion gov\u00aderns the rate of hydro\u00adgen adsorp\u00adtion and thus the over\u00adall HER\/HOR kinet\u00adics by mod\u00adu\u00adlat\u00ading the poten\u00adtial of zero charge of oxide sup\u00adports in acid and base.
