ʻO ka hoʻomākaukau ʻana o ka hana kiʻekiʻe i kākoʻo ʻia i ka nano-gold catalysts e noʻonoʻo nui i ʻelua ʻaoʻao, ʻo ka hoʻomākaukau ʻana o ke gula nano, e hōʻoiaʻiʻo ana i ka hana catalytic kiʻekiʻe me ka liʻiliʻi liʻiliʻi, a ʻo ka mea ʻē aʻe ke koho ʻana i ka mea lawe, pono e loaʻa kahi kikoʻī kikoʻī nui. wahi a me ka hana maikaʻi.ka wettability kiʻekiʻe a me ka pilina ikaika me nā nanoparticles gula i kākoʻo ʻia a hoʻopuehu nui ʻia lākou ma ka ʻili o ka mea lawe.

ʻO ka mana o ka mea lawe i ka hana catalytic o Au nanoparticles ka mea nui i hōʻike ʻia i loko o kahi kikoʻī o ka ʻili, wettability o ka mea lawe ponoʻī a me ke ʻano o ka pilina ma waena o ka mea lawe a me nā nanopowders gula.ʻO kahi mea lawe me kahi SSA nui ka mea e pono ai no ka hoʻopuehu kiʻekiʻe o nā ʻāpana gula.ʻO ka wettability o ka mea lawe e hoʻoholo inā e hōʻuluʻulu ka catalyst gula i loko o nā ʻāpana gula nui i ka wā o ke kaʻina calcination, a laila e hōʻemi ana i kāna hana catalytic.Eia kekahi, ʻo ka ikaika o ka launa pū ʻana ma waena o ka mea lawe a me ka Au nanopowders he kumu nui e pili ana i ka hana catalytic.ʻOi aku ka ikaika o ka pilina ma waena o nā ʻāpana gula a me ka mea lawe, ʻoi aku ka kiʻekiʻe o ka hana catalytic o ka catalyst gula.

I kēia manawa, kākoʻo ʻia ka hapa nui o ka nano Au catalysts.ʻAʻole kūpono ka noho ʻana o ke kākoʻo i ka paʻa ʻana o nā ʻano gula ikaika, akā he mea nui hoʻi i ka hoʻolaha ʻana i ka hana o ka catalyst holoʻokoʻa ma muli o ka pilina ma waena o ke kākoʻo a me nā nanoparticles gula.

Hōʻike ka nui o nā hualoaʻa noiʻi i ka nano-gula i hiki ke hoʻokalakupua i nā ʻano hopena kemika, a manaʻo ʻia e hoʻololi piha a ʻāpana paha i nā catalysts metala makamae e like me Pd a me Pt ​​i nā kula o ka synthesis kemika maikaʻi a me ka mālama kaiapuni. , e hōʻike ana i nā manaʻo noiʻi ākea:

1. koho koho

ʻO ka oxidation koho o nā waiʻona a me nā aldehydes, ka epoxidation o nā olefins, ka koho koho ʻana o nā hydrocarbons, synthesis o H2O2.

2. Ka hoʻoheheʻe hydrogen

Hydrogenation o olefins;koho hydrogenation o unsaturated aldehydes a me ketones;koho hydrogenation o nitrobenzene pūhui, kaʻikepili hōʻike i ka Au / SiO2 catalyst me ka nano-gula hoʻoili o 1% hiki ke hoomaopopo i ka efficient catalysis o kiʻekiʻe-maʻemaʻe halogenated aromatic amines hydrogenation synthesis hāʻawi i ka hou hiki ke hoʻoponopono i ka pilikia o ka dehalogenation ma catalytic. hydrogenolysis i ka hana ʻoihana o kēia manawa.

Nano Au catalysts ua hoʻohana nui 'ia i loko o biosensors, kiʻekiʻe-efficiency catalysts, a me ke gula i maikai kemika paʻa.ʻO ia ka mea paʻa loa ma waena o nā mea hui VIII, akā hōʻike nā nanoparticles gula i ka hana catalytic maikaʻi loa ma muli o nā hopena liʻiliʻi, nonlinear optics, etc.

Ma ka catalyzing like reactions, nano gula catalyst i haʻahaʻa hopena wela a me ka kiʻekiʻe selectivity ma mua o ka laulā metala catalysts, a me kona haʻahaʻa-mahana catalytic hana kiʻekiʻe.ʻOi aku ka kiʻekiʻe o ka hana catalytic ma ka mahana hopena o 200 °C ma mua o ka mea kūʻai CuO-ZnO-Al2O3 catalyst.

1. CO oxidation pane

2. Haʻahaʻa wela wai kinoea hoʻololi pane

3. Liquid-phase hydrogenation pane

4. ʻO nā hopena hoʻoheheʻe wai-phase, me ka ethylene glycol oxidation e hoʻohua ai i ka ʻakika oxalic, a me ka koho koho ʻana o ka glucose.
