“…Although strong metal-support interactions decrease the reducibility of metallic Co and Ni particles, these strong interactions produce higher values of exposed surface metallic active sites, which increase the catalytic performance. On the contrary, small particles of AlZr and AlTi increase the surface area, but favour the metal cations mobility over the support surface, which allows the sintering of the metallic particles during the calcination process [25]. Metal sintering decreases metal exposure, and consequently, decreases the bio-ethanol conversion and hydrogen production.…”

“…Some of them are highlighted here: (1) the single crystal nature and faceting improves the properties of the supported catalytically-active metals through the resulting nickel cluster morphology; (2) ability to produce well-defined surface facets therefore higher concentration of desired sites [25]; (2) potentially enhance metal-support interactions; (3) nanowire support undergo less sintering than conventional supports [26,27]; and (4) nanoparticle on nanowire morphology presents an easier diffusion pathway for sulfur transfer from supported clusters to underlying support to maintain a high surface concentration of active nickel sites for deep desulfurization activity. Even though the nanowire supports are predicted to have the above-mentioned advantages, there are no studies for both deep HDS and aromatic hydrogenation using catalysts made from nanowire powders.…”

“…Показано, что недос-татком вышеописанного процесса является наличие в продуктах реакции значительного количества мо-ноокиси углерода (до 10 об.%), что не позволяет ис-пользовать получаемую богатую водородом смесь для питания топливных элементов на протонопрово-дящих мембранах без дополнительной очистки. В то же время известны работы [19][20][21][22][23] по каталитиче-скому водно-паровому реформингу этанола при низ-ких температурах, в которых использовались катали-заторы, нанесенные на оксид цинка. Исследовались смеси с большим содержанием воды, близкие по со-ставу к биоэтанолу.…”

“…Исследовались смеси с большим содержанием воды, близкие по со-ставу к биоэтанолу. Утверждается [19][20][21], что исполь-зование оксида цинка в качестве носителя приводит к возможности протекания реакции водно-парового реформинга ацетальдегида с образованием моноокиси углерода и водорода без его предварительного разло-жения на метан и моноокись углерода:…”
