An investment horizon of 1 year is considered “short-term”. Investments that meet the criteria for Short-term are essentially low risk- low return kind of investments.
Also, what number would you consider “higher returns”? In my opinion, if your investment horizon is 1 year, you should consider Short or Ultra Short term Bond Funds. Liquid funds are also a good option.
You may not get a massive return, but atleast your capital is relatively safe.
