Khorozov served as president of the Ice Hockey Federation of Ukraine, and its forerunner federation from 1965 to 1997. He became involved in ice hockey by organizing a team at his son's school. He was introduced to Dmitry Boginov in 1963, who was the first coach of the new Dynamo Sports Club hockey team, which later became Sokil Kiev. Boginov invited Khorozov into the national hockey workings, and Khorozov became president of the federation in 1965. Khorozov focused on creating schools across Ukraine to teach hockey, and recruited reputable coaches to develop skills. He secured funding from the State Committee for Construction in the 1970s and led the construction of ice hockey rinks for youths. He also negotiated support from the trade unions in Ukraine to sponsor teams at all ages to play in the new rinks. He was aided by political friends including Vitaliy Masol and Vitold Fokin, and fought to increase wages for successful players, and aimed to reduced their housing costs. Players referred to Khorozov as a "public president" in the sense that he was approachable by all, and wanted to include and encourage everyone. Khorozov championed the cause of youth being healthy both physically and spiritually. He brought in strong competition for teams in Ukraine by using his contacts in Russia. By the middle 1980s, local-grown talent began to mature, and play on Sokil Kiev and the Soviet Union national ice hockey team. By 1985, Sokil Kiev won the bronze medal in the Soviet Championship League, and became one of the more popular teams in the Soviet Union. This success led Khorozov to assist in the development of sports tourism, and the Olympic training center in Koncha-Zaspa. Khorozov was succeeded as president of the Ice Hockey Federation of Ukraine by Oleksandr Omelchenko. In a 2006 interview, Khorozov said that choosing Omelchenko as his successor was a mistake, since state funding for hockey was ended, and its development structure was abandoned.
Khorozov was inducted into the IIHF Hall of Fame as a builder in 2006. The announcement was made during the 2006 Men's World Ice Hockey Championships in Riga, and on 11 May 2006, he became the first Ukrainian in the IIHF Hall of Fame, and as of 2019 is the only representative from his country. Khorozov is referred to as the father of ice hockey in Ukraine, and was made an honorary president of the Ukrainian Ice Hockey Federation.
