1.我烧催化剂时，由于同事们也要用炉子，炉子有时没完全冷却到室温，这影响吗？ I am sure it will influence.
2.我的电流速率快到10，是不是电流速率太大了，通过实验，烧成灰黑色的催化剂效果明显不好，怎样避免这种情况呢？
You should use the programmed-temperature to controll the rising speed.
浸渍法一般用搅拌 to get homogeneous phase.
有时烧的催化剂呈现灰黑色，有时是土的颜色，There are two possible resons:
First, it is due to the oven without controlling termperature exactly.
Second, it is due to the aggregation on the surface.
