Oznake: titanov dioksid;velika specifična površina;fotokataliza;nanodelci;titanium dioxide;high surface area;photocatalysis;nanostructured particles;
Hydrothermal reactions represent a simple and efficient method for the preparation of nanostructured TiO$_2$ particles that could be of interest as photocatalysts or catalytic supports. Although the particle size is in the range of 2–5 µm, the nanostructures composing the particles ensure a large sp ...

In the present study, a Bi$_2$WO$_6$/ZnWO$_4$ photocatalyst was successfully constructed by a modified hydrothermal synthesis method with different molar concentrations of Bi$_2$WO$_6$ with respect to ZnWO$_4$. The variation in molar concentrations of Bi$_2$WO$_6$ changed the photocatalytic properti ...

V zadnjih desetletjih postaja dostop do čiste vode vse večja težava, ki jo lahko pripišemo eksponentni rasti prebivalstva in industrializaciji, zaradi česar se je pojavila potreba po ponovni uporabi očiščenih vod. V ta namen je bilo razvitih veliko metod za čiščenje odpadnih voda, ki pa so lahko pri ...

When wood is thermally modified, several chemical reactions take place that change the chemical and physical properties of the wood. These changes correlate with the degree of modification, which is mostly a function of the temperature and duration of modification, and consequently with the mass los ...
