1. 1. Chromia-Alumina Thin Films from Alkoxide Precursors : From Precursor Synthesis to Deposition and Characterisation

   University essay from Uppsala universitet/Oorganisk kemi

   Author : Elina Elvelo; [2023]
   Keywords : alkoxide; synthesis; thin film; coating; alumina; chromia; spinodal decomposition;

   Abstract : A hetero-bimetallic alkoxide CrAl3(OiPr)12 was synthesised through metathesis of achromium(III)chloride THF complex (CrCl3 . 3 THF) and 3 KAl(OiPr)4.It was used as a single sourceprecursor to make oxide powders and films with 1:3 chromium/aluminium compositionthrough sol-gel synthesis.

3. 2. Study of Reverse Water Gas Shift reaction using bimetallic catalysts on active supports : The case of unpromoted and K-promoted FeCu/CeO2

   University essay from KTH/Kemiteknik

   Author : Carlo Sala; [2022]
   Keywords : CO2 utilization; RWGS; catalyst; active catalytic support; characterization; CO2 användning; RWGS; katalysator; aktiva katalysatorbärare; karakterisering;

   Abstract : Reverse Water Gas Shift Reaction (RWGS) är en attraktiv lösning för CO2-använding och minskning av utsläppen i atmosfären. Denna reaktion begränsas av termodynamiken och det finns problem med storskalig tillämpning. För att förbättra genomförandet av processen krävs utveckling av en effektiv katalysator. READ MORE

4. 3. The Effect of Electrode Composition on the Composition of Binary Ag/Au Nanoparticles Produced by Spark Ablation

   University essay from Lunds universitet/Fasta tillståndets fysik; Lunds universitet/Fysiska institutionen

   Author : Linnéa Jönsson; [2021]
   Keywords : Nanoparticles; Spark Ablation; Technology and Engineering;

   Abstract : Synthesis of nanoparticles with high control of the particle composition, high purity and high throughput is of great interest for multiple applications such as catalysis, medicine, energy storage, sensoring, and electronics. As an alternative method to the traditionally used chemical synthesis routes, gas-phase methods have gained attention due to the avoidance of solvents resulting in higher purity of the particles, but also due to the more flexible choice of materials.

5. 4. Tuning the composition of metallic nanoparticles for catalytic applications

   University essay from KTH/Kemi

   Author : Anthony Ropp; [2021]
   Keywords : catalysis; nanoparticles; frustrated Lewis pairs; synthesis; core-shell;

   Abstract : Industries’ interest in nanomaterials is tremendous and catalysis is one of their applications. Catalysts allow reactions to occur under milder conditions, avoiding committing excessive heat or pressure to foster reactions. READ MORE

6. 5. Investigation of catalyst composition for cobalt and iron catalyst on the chirality of grown single walled carbon nanotubes

   University essay from Umeå universitet/Institutionen för fysik

   Author : Saeed Motaragheb Jafarpour; [2017]
   Keywords : ;

   Abstract : The synthesis of type-enriched semiconducting or metallic single-walled carbon nanotubes (sc/m-SWCNTs) with high quality by means of catalytic chemical vapor deposition (CCVD) are essential prerequisites for implementing of SWCNTs into nanodevices. In particular, the Fe−Co bimetallic catalysts system is promising due to its ability to grow SWCNTs by CCVD. READ MORE
