one day visa for my stopover in Beijing airport

Hi I am Sudhir Kumar from India - presently visiting Sydney(Australia) - on my way back to Delhi on 19 sep I have a stayover at Beijing airport for 15 hours. My question is that can I get a Visa for a Day to move out from airport to visit some local tourist spots and also what is the visa charges for one day and can it be paid in US $ ?
