Estudio del mecanismo de reacción de la oxidación de isopropanol sobre óxidos mixtos de Mn-Ti mediante espectroscopía FT-IR y cromatografía de gases

open access: yesBoletín de la Sociedad Española de Cerámica y Vidrio, 2000
Several samples of TiO2 (anatase)-supported Mn oxide have been prepared by a wet impregnation method, named as XMn- TiO2 (with X = 0.5, 1.0, 1.5 and 2.0, the theoretical monolayer fractions). All samples were characterised by conventional techniques.

CO Spillover Is Not a Promoter for C─C Bond Formation in CO2 Electroreduction on Cu‐Ag Bimetallic Catalysts

open access: yesAdvanced Science, EarlyView.
CO spillover via the Cu‐Ag interface does not promote C‐C coupling. ABSTRACT Cu‐based bimetallic catalysts have been shown to improve the multi‐carbon (C2+) selectivity in CO2 electroreduction, with the assumption that CO spillover from the CO‐selective catalysts to adjacent Cu domains via their bimetallic interface promotes C–C coupling. Here, through

Systematically Engineering for Efficient Production of 3‐Methyl‐1‐Butanol in Escherichia coli

open access: yesAdvanced Science, EarlyView.
An integrated metabolic engineering strategy was established for high‐level 3‐methyl‐1‐butanol biosynthesis in Escherichia coli. Molecular dynamics‐guided semi‐rational engineering of dihydroxyacid dehydratase uncovered and relieved key catalytic bottlenecks, while adaptive laboratory evolution enhanced strain robustness.

EDTA‐Functionalized Nanoscale Metal–Organic Framework for Onco‐Cardiology via Radiochemotherapy Synergy and Spatiotemporally Matched Iron Chelation

open access: yesAdvanced Science, EarlyView.
Doxorubicin (DOX)‐induced cardiotoxicity is a major limitation to its broader clinical application, while cardioprotective interventions often risk reducing the anticancer efficacy of DOX. To address these challenges, this work constructs an EDTA‐functionalized metal–organic framework that enhances tumor therapy and provides efficient cardioprotection ...

Liquid Bismuth Catalyst Enables High‐CO‐Selectivity in CO2 Hydrogenation

open access: yesAdvanced Science, EarlyView.
This work introduces a dynamic liquid bismuth catalyst for efficient CO2‐to‐syngas conversion. Stabilized molten Bi nanodroplets on a defective VOx support enable a reversible Bi3+/Bi0 redox cycle at moderate temperatures. Mechanistic insights reveal that Ni‐Bi dual sites synergistically activate H2 and cleave CO2, leading to high CO selectivity ...

Combining Electrochemical Reduction with Biosynthesis for Directed Conversion of CO2 into a Library of C3 Chemicals

open access: yesAdvanced Science, EarlyView.
In the H‐type electrolytic cell, carbon dioxide is reduced to acetic acid via electro‐microbial catalysis. The simply processed acetic acid is further converted through biological fermentation into high‐value‐added products, including acrylic acid, L‐lactic acid, and β‐alanine.

Synthetic C1 metabolism in Pseudomonas putida enables strict formatotrophy and methylotrophy via the reductive glycine pathway

open access: yesmBio
Formate and methanol are promising alternatives to sugar-based feedstocks for biotechnological applications. These one-carbon (C1) substrates can be sustainably produced from CO2 and renewable electricity and assimilated by both native and engineered ...
