The Z-Scheme of Electron Transport in Photosynthesis01:34

The Z-Scheme of Electron Transport in Photosynthesis

15.1K
The light reactions of photosynthesis assume a linear flow of electrons from water to NADP+. During this process, light energy drives the splitting of water molecules to produce oxygen. However, oxidation of water molecules is a thermodynamically unfavorable reaction and requires a strong oxidizing agent. This is accomplished by the first product of light reactions: oxidized P680 (or P680+), the most powerful oxidizing agent known in biology. The oxidized P680 that acquires an electron from the...

Oxidation of Alkenes: Syn Dihydroxylation with Potassium Permanganate

17.9K
Alkenes can be dihydroxylated using potassium permanganate.  The method encompasses the reaction of an alkene with a cold, dilute solution of potassium permanganate under basic conditions to form a cis-diol along with a brown precipitate of manganese dioxide.

Oxygenic Photosynthesis01:26

Oxygenic Photosynthesis

953
Oxygenic photosynthesis is a fundamental process in which light energy is harnessed to drive the oxidation of water, leading to the production of molecular oxygen (O₂), adenosine triphosphate (ATP), and nicotinamide adenine dinucleotide phosphate (NADPH). This process is essential for sustaining aerobic life on Earth and is primarily carried out by cyanobacteria, algae, and plants. The core of oxygenic photosynthesis lies in the thylakoid membranes, where chlorophyll pigments facilitate...

Oxidative Cleavage of Alkenes: Ozonolysis

13.5K
In ozonolysis, ozone is used to cleave a carbon–carbon double bond to form aldehydes and ketones, or carboxylic acids, depending on the work-up.
Ozone is a symmetrical bent molecule stabilized by a resonance structure.

Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide02:44

Oxidation of Alkenes: Syn Dihydroxylation with Osmium Tetraoxide

13.4K
Alkenes are converted to 1,2-diols or glycols through a process called dihydroxylation. It involves the addition of two hydroxyl groups across the double bond with two different stereochemical approaches, namely anti and syn. Dihydroxylation using osmium tetroxide progresses with syn stereochemistry.

Area of Science:

  • Materials Science
  • Catalysis
  • Green Chemistry

Background:

  • Photocatalytic conversion of biomass is a promising sustainable route for producing chemicals.
  • Controlling selectivity in biomass valorization is difficult due to complex structures and competing reactions.

Purpose of the Study:

  • To develop a wavelength-controlled photocatalytic strategy for regulating biomass conversion selectivity.

Main Methods:

  • Utilized black TiO2 with continuous defect energy levels as a model photocatalyst.
  • Employed wavelength-dependent excitation of defect states to achieve adaptive oxidative behavior.
  • Investigated the selective conversion of xylose to xylonic acid under visible and UV light.

Main Results:

  • Achieved selective conversion of xylose to high-value xylonic acid under visible light.
  • Avoided over-oxidation to low-value C1 products, which occurred under UV irradiation.
  • Demonstrated that tunable photooxidation capability of defect states suppresses non-selective hydroxyl radical production.

Conclusions:

  • Established a correlation between defect energy-level distribution and selective biomass oxidation.
  • Developed a self-tuning approach for directional biomass conversion via catalyst design.
  • Validated the strategy's broad applicability in selective chemical synthesis using adaptive photocatalysis.
