Abstract：

The　development　of　effective　Ru　catalyst　for　ammonia　synthesis　is　of　important　practical　value　and　scientific　significance　because　of　the　wide　application　of　ammonia　as　a　fertilizer　and　its　promising　applications　in　the　renewable　energy.　Generally,　ZrO2　was　regarded　as　an　inferior　support　for　Ru　catalyst　used　in　ammonia　synthesis.　Here　we　prepare　ZrO2　with　monoclinic　phase　and　carbon　species　from　ZrCl4　following　the　preparation　route　of　UiO-66　as　well　as　ammonia　treatment.　Owing　to　the　presence　of　a　larger　amount　of　hydrogen　adsorption　as　well　as　the　easier　desorption　of　hydrogen　species,　the　ill　effect　of　hydrogen　species　on　the　nitrogen　adsorption-desorption　and　ammonia　synthesis　can　be　effectively　alleviated.　The　resulting　ZrO2-supported　Ru　catalyst　showed　4　times　higher　ammonia　synthesis　activity　than　the　conventional　Ru/ZrO2　obtained　from　zirconium　nitrate.　©　2022
