The invention relates to a sensor material which has electrochemical sensing and colorimetric sensing performances at the same time as well as is applied to qualitative and quantitative determination of glucose or hydrogen peroxide. The material comprises hydrotalcite nanosheet arrays containing cobalt and iron, a simple one-step electrosynthesis method is used, and the cobalt-iron hydrotalcite nanosheets vertically grow on a conductive substrate. The sensor material is used as a catalase-like inorganic nano-material which has good color changing responses in colorimetric sensing analyses of glucose and hydrogen peroxide, linear range of the catalase-like glucose biosensor is 0-800[mu]M, and after 4 times of circulation and repeated usage, the sensing performance is kept at 90% or above; the sensor material has good anti-interference performances for ascorbic acid, dopamine, urea, etc.
