Methods of providing a homogeneous or homogeneous catalytic coating on an inorganic fibrous substrate include the use of a vacuum coated substrate, an improved coating solution or mixture, and/or a drying process to prevent migration of a metal catalyst precursor to the outer surface and edge of the inorganic fibrous substrate. The method may include adding components to a first coating solution or mixture prior to coating an inorganic fibrous substrate; applying a second coating solution or mixture to the coated inorganic fibrous substrate; drying the coated inorganic fibrous substrate under ambient conditions, under controlled conditions or with microwave radiation; or optimizes the amount of salt, water or organic solvent in the coating solution. 在无机纤维基底上提供均质或均匀催化涂层的方法包括使用真空涂布基底、改进的涂料溶液或混合物和/或干燥方法以防止金属催化剂前体迁移到无机纤维基底的外表面和边缘。该方法可包括在涂布无机纤维基底之前将组分添加到第一涂料溶液或混合物中；将第二涂料溶液或混合物施加到涂布的无机纤维基底上；在环境条件下、在受控条件下或用微波辐射将涂布的无机纤维基底干燥；或优化涂料溶液中的盐、水或有机溶剂的量。
