We have prepared Janus CuO/CuS colloids by a precipitation reaction in the water phase of a Pickering emulsion. The relative proportion of CuO to CuS in the Janus colloids can be tailored by variation of the polarity of the oil phase. The Janus CuO/CuS colloids did not rotate at the emulsion interface. Our findings are important to understand the fundamentals of Pickering emulsions and will also help in designing appropriate approaches to synthesize Janus colloids and other new materials in Pickering emulsions.
