技术定义与适配语境
典型 载体/稳定剂 会按材料、尺寸公差、适配关系和失效风险在 化学制造 中评估。

A carrier/stabilizer is a solid material, often porous, used to support and disperse catalytic active components (e.g., metals, enzymes) to enhance their stability, activity, and selectivity. It prevents agglomeration, provides mechanical strength, and facilitates catalyst recovery and reuse. Common carriers include alumina, silica, zeolites, and carbon-based materials.

定义
A carrier/stabilizer is a solid material, often porous, used to support and disperse catalytic active components (e.g., metals, enzymes) to enhance their stability, activity, and selectivity. It prevents agglomeration, provides mechanical strength, and facilitates catalyst recovery and reuse. Common carriers include alumina, silica, zeolites, and carbon-based materials.
工作原理
The carrier provides a high surface area substrate for the deposition of catalytic active species. Through physical adsorption, chemical bonding, or encapsulation, the active components are anchored onto the carrier surface, preventing sintering and deactivation. The carrier may also participate in the reaction by providing acid/base sites or influencing electron transfer.
