In this article considered the concept of water tourism. The water tourism as a special type of recreation have been studied. The conditions for the development of water tourism in the South-East part of the Republic of Sakha (Yakutia) are described. Scientific and methodological foundations have been developed for creating digital maps of...

The highway "Kolyma" is one of the most promising tourist sites of Yakutia. It crosses a variety of landscapes, has a unique history, available to the public. This article concerns on the evaluation of tourist potential of the territory, "Kolyma", adjacent to the road will highlight attractive from a touristic spot.

This article describes forest fires in Yakutia as one of the main types of natural hazards, as well as the factors of their occurrence and proposes methods of geoinformation modeling of forest fire risk in the Republic of Sakha (Yakutia). Forests of Yakutia occupy a significant area. Forest fires annually cover an area of hundreds of thousands...

One of the most trending topics in catalysis recently is the use of renewable sources and/or non-waste technologies to generate products with high added value. That is why, the present review resumes the advances in catalyst design for biomass chemical valorization. The variety of involved reactions and functionality of obtained molecules...

Gold is without a doubt the best known metal for chemical oxidation. The noblest of the noble metals gained its place because of its resistance to overoxidation, low temperature of operation, especially in gas-phase oxidation, and fairly good selectivity when required. The aim for sustainable development and the need for new technologies open...

Following UNESCO's official celebration of the International Day of Women and Girls in Science, Frontiers in Chemistry decided to run a special issue "Women in Science: Chemistry". Indeed, although science and gender equality are essential to ensure sustainable development, less than 30% of researchers worldwide are women.

The effect of gold presence on carbon monoxide oxidation and ethanol steam reforming catalytic behavior of two Ce-Zr-Co mixed oxides catalysts with a constant Co charge and different Ce/Zr ratios was investigated. The Ce-Zr-Co mixed oxides were obtained by the pseudo sol-gel like method, based on metallic propionates polymerization and thermal...

The present work showcases the versatility of nanogold systems supported on Zn-doped ceria when applied in two important environmental processes, the total CO oxidation, and the liquid phase oxidation of glucose to gluconic acid. In the CO oxidation the suitability of these materials is clearly demonstrated achieving full conversions even at...

The influence of the crystal structure and chemical nature of some ionic liquid/phosphomolybdate hybrids on their catalytic activity in the epimerization of glucose is studied. A clear evidence for structure-activity relationship is found. The inorganic part of the hybrid assures the active sites for the reaction; meanwhile the organic cation...

The WGS reaction over multicomponent Au/Ce1-xCuxO2/Al2O3 catalysts is studied in this work. The systems are carefully designed aiming to take advantage of every active phase included in the formulation: gold, ceria and copper. Special emphasis is given to the CeO2-CuO synergy and its influence on the displayed catalytic performance with and...

A series of mesoporous carbonaceous materials were synthesized by the nanocasting technique using boehmite as a template and glucose as a carbon precursor. After pyrolysis and template removal, the resulting material is a mesoporous carbon that can be additionally doped with N, B and K during prepyrolysis impregnation. In addition, the...

In this work the development of gold catalysts, essentially based on γ-alumina with small superficial fraction of Ce-Fe mixed oxides as support for the low temperature CO oxidation is proposed. Characterization results obtained by means of TEM, OSC, XPS, UV-Vis spectroscopy and H2-TPR are employed to correlate the activity data with the...
