Abstract
processo para fácil eletrossíntese de grafeno a partir de co2. a presente invenção refere-se à produção de grafeno a partir de co2 através de processos de eletrólise e esfoliação. uma modalidade é um método para produção de grafeno compreendendo (i) realização de eletrólise entre um anodo de eletrólise e um catodo de eletrólise em um eletrólito carbonato fundido para gerar nanomaterial de carbono sobre o catodo, e (ii) esfoliando eletroquimicamente o nanomaterial de carbono de um segundo anodo para produzir grafeno. a etapa de esfoliação produz grafeno em alto rendimento do que reações de esfoliação de grafite convencionais, mais espessas. co2 pode ser o único reagente usado para produzir o valioso produto como grafeno. isto pode incentivar utilização de co2, e diferente de produtos alternativos fabricados a partir de co2 tal como monóxido de carbono ou outros combustíveis tal como metano, uso do produto grafeno não libera este gás de estufa na atmosfera.
