说明

General description

氧化铈(IV)(CeO₂)，又称氧化铈或二氧化铈，是稀土金属铈的氧化物。本品为白色至黄色纳米粉末，粒径小于25 nm(BET)，具有高比表面积和反应活性。广泛应用于催化、电化学、玻璃和陶瓷领域。CeO₂广泛用于制造汽车催化剂，减少有害排放。还用于生产高级的陶瓷和玻璃抛光产品，也是很多化学反应的催化剂。它独特的性质适合制作固体氧化物燃料电池，也可用作防晒产品中的紫外吸收剂。

我们竭诚为您带来符合一项或多项绿色化学12项原则要求的绿色替代产品。本品旨在用于分子太阳能热能储存系统(MOST)，并已经过能效优化。点击此处以获取更多信息。

Application

CeO₂ 添加到 CuO/TiO₂ 中会增加比表面积并抑制高温下的烧结和孔径增长。

CeO₂纳米粉末可用于制作固体氧化物燃料电池(SOFC)，因其具有离子导电性和高温稳定性。也可用于制造电池和超级电容器，有助于提高性能。CeO₂也用作玻璃和半导体行业的抛光粉。它精细的粒径和硬度有助于获得高抛光平整度的光学元件。

Advances in Materials for Solid Oxide Fuel Cells

As with all types of fuel cells, a Solid Oxide Fuel Cell (SOFC) is capable of efficiently transforming chemical energy into electrical energy.

Materials for Clean H² Production from Bioethanol Reforming

Hydrogen is one of the most important resources in providing food, fuel, and chemical products for our everyday life. Sustainable catalytic hydrogen production from bioethanol has gained significant attention in recent years due to globally diminishing fossil fuel supplies, which have necessitated the search for new chemical feedstocks.

Development of industrial catalysts for sustainable chlorine production.

Cecilia Mondelli et al.

Chimia, 66(9), 694-698 (2012-12-06)

The heterogeneously catalyzed gas-phase oxidation of HCl to Cl(2) offers an energy-efficient and eco- friendly route to recover chlorine from HCl-containing byproduct streams in the chemical industry. This process has attracted renewed interest in the last decade due to an

In situ supported MnO(x)-CeO(x) on carbon nanotubes for the low-temperature selective catalytic reduction of NO with NH3.

Dengsong Zhang et al.

Nanoscale, 5(3), 1127-1136 (2013-01-04)

The MnO(x) and CeO(x) were in situ supported on carbon nanotubes (CNTs) by a poly(sodium 4-styrenesulfonate) assisted reflux route for the low-temperature selective catalytic reduction (SCR) of NO with NH(3). X-Ray diffraction (XRD), transmission electron microscopy (TEM), high-resolution TEM (HRTEM)

Au25 nanocluster-catalyzed Ullmann-type homocoupling reaction of aryl iodides.

Gao Li et al.

Chemical communications (Cambridge, England), 48(98), 12005-12007 (2012-11-07)

The Au(25)(SR)(18)/CeO(2) nanocluster catalyst showed high activity in the homocoupling of aryl iodides (e.g. up to 99.8% yield with iodobenzene) and excellent recyclability.
