Abstract

processo para produzir um sol concentrado de nano titânia, sol concentrado aquoso de nano titânia, composição catalítica, métodos para proteger uma composição catalítica, métodos para proteger uma superfície de um substrato contra a radiação por uv e para degradar ou inativar contaminantes ou poluentes que contatam uma superfície, e, revestimento ou artigo. a presente invenção fornece um processo para a produção de um sol concentrado aquoso de nano titânia na faixa de ph suave (4,0 a 10,0) constituído pelo contato de um sol de nano titâna ácido com um dispersante e com um agente alcalinizante, e subsmeter-se o sol de nano titânia à filtração por membrana até que o sol de nano titânia contenha mais de 300 g de nanopartículas de tio~ 2~/dm^ 3^. o sol de nano titânia poderá ainda ser submetido a um tratamento de revestimento em qualquer das etapas do processo descrito acima. o sol concentrado aquoso de nano titânia desta apresentação é adequado para uso em uma variedade de aplicações, incluindo o fornecimento de proteção contra uv e a degradação fotoquímica ou inativação de contaminantes.
