“…5, the photocatalytic activities for hydrogen production over the Nb 2 O 5 materials are shown. The photocatalytic activity of MN400 enhanced significantly by loading Pt cocatalyst, which forms active species on the catalyst's surface [39]. The Pt particles were detected in the TEM image (Fig.…”

“…Deposition of noble metal nanoparticles, and particularly platinum, may play a beneficial effect on the efficiency of a photocatalytic process, [50][51][52] due to the occurrence of at least two different effects. On one hand, particularly for gas evolution and especially for H 2 evolution, it has been found that the presence of a noble metal with the role of a hydrogenation catalyst facilitates kinetics of H 2 gas formation from H 2 O.…”

The shortage of fossil fuels and the need to find alternative renewable and sustainable fuels for transportation are triggering an increasing interest in the photocatalytic reduction of CO 2 . In this review, we have focused on titanium containing photocatalysts that effect the reduction of CO 2 to fuels. The various products that are more generally formed are CH 4 , CH 3 OH, CO as well as HCOOH. This review has been organized primarily depending on the type of titanium material used as the photocatalyst. The list includes pure TiO 2 as well as metal-and non metal-doped titania, noble metals supported on titania and micro-/mesoporous titanosilicates or porous matrices containing titania clusters. In a general introduction we comment on the limitations of the current approaches and the various possibilities and conditions for performing the irradiation. In a final section, we also give our view on future developments and open issues to be addressed in this field.

“…Due to the difficulty of measurements at elevated temperature, a large uncertainty of the properties exists. [26] The following crucial slag properties are required for CFD modeling, which are extracted from literature: electric conductivity, [26][27][28][29][30][31][32] thermal conductivity, [27,33,34] viscosity, [19,26,27,[35][36][37] density, [2,19,26,27,[37][38][39][40] specific heat, [41] surface tension, [19,27,40,42] emissivity, [34,43] and liquidus/solidus temperature. [35,44] The physicochemical properties of the conventional slags can vary strongly as function of composition and temperature ( Table 1).…”

The Electroslag Remelting (ESR) is an advanced technology for the production of high quality materials, for example, hot work tool steels or nickel base alloys. In the past years, several models are developed aiming to predict the way in which the operational parameters affect the structure and chemical composition of the final ESR ingot. Proper modeling of this process depends on the ability of the model to predict the Multiphysics resulting from the complex coupling between many physical phenomena. This review includes the main findings starting from the 1970's, with a special focus on the results obtained in the period of 1999-2017. The difficulties related to the poorly known physical properties of ESR slags are discussed. Then, the main achievements in the field of electromagnetism, fluid flow, heat transfer, and solidification are also summarized. The review finishes by presenting the special topics representing the actual scientific frontiers, such as the physics of mold current, the importance of multiphase phenomena, and the difficulties in predicting the electrode melting rate.
