                           OXFORD CATALYSTS GROUP PLC
                     ('Oxford Catalysts' or 'the Company')

                     Appointment of Chief Financial Officer

Oxford Catalysts, the leading catalyst innovator for clean fuels, is pleased to
announce that it has appointed Susan Robertson, FCA as Chief Financial Officer
('CFO'), with immediate effect.

Susan joins Oxford Catalysts following seventeen years at The BOC Group (now
Linde Group). From its inception in 2003 until 2006, Susan was Vice President
and CFO of Japan Air Gases (JAG), then a £700m turnover joint venture owned by
The BOC Group and Air Liquide.

At JAG, Susan helped to successfully integrate the two founding JV companies,
realising £25m p.a. of synergies, whilst identifying and managing the sale of
non-core assets. She also created and managed a new high performing finance
function comprising 38 staff, at the same time reducing costs by 30%.

During her time at JAG, Susan presided over a significant rise in shareholder
return achieved through improved profitability, increased dividends and the
restructuring of equity capital to debt financing.

Susan's previous experience with BOC includes finance, commercial and business
development roles in the UK, globally and at head office. She trained as a
chartered accountant with Arthur Andersen and has an economics degree from
Cambridge University.

As CFO, Susan will be functionally replacing Paul Barnes who has served as
part-time Finance Director since the Group's admission to AIM in April 2006.
Paul will be stepping down from the Board after a suitable handover period.

Commenting on her appointment, Susan Robertson said:

'I'm excited to be joining this dynamic organisation with such a bright future.
I look forward to using my financial and industry experience to help Oxford
Catalysts continue its rapid growth in revenue and accelerate towards
profitability.'

Commenting on the appointment, Roy Lipski, Chief Executive of Oxford Catalysts
said:

'I am thrilled to welcome Susan Robertson to the team as full time CFO. Susan
has substantial financial and commercial experience gained in a multi-national
blue-chip environment, within a relevant industry area. We look forward to her
playing a pivotal role in the continued development, growth and success of
Oxford Catalysts.'

Notes to Editors


Oxford Catalysts Group PLC, the leading catalyst innovator for clean fuels,
designs and develops specialty catalysts for the generation of clean fuels from
both conventional fossil fuels and certain renewable sources such as biomass.
Its patent-pending technology is the result of almost 20 years of research at
the University of Oxford's prestigious Wolfson Catalysis Centre, headed by
Professor Malcolm Green, one of the world's most respected inorganic chemists.
Oxford Catalysts was founded by Professor Green and Dr Xiao in October 2004 and
was admitted to trading on the AIM market of the London Stock Exchange on 26th
April 2006, having raised £15m before expenses from a solid base of
institutional investors.

Oxford Catalysts' strategy is to license its catalysts for commercial
application by entering into co-development partnerships with leading
manufacturers, producers and suppliers in the petroleum, petrochemicals, fuel
cells, biogas, steam applications and catalysis markets.

Oxford Catalysts has two key platform technologies. The first is for a novel
class of catalysts made from metal carbides which, for certain reactions, can
match or exceed the benefits of traditional precious metal catalysts at a lower
cost. Applications of these metal-carbide catalysts include the removal of
sulphur from crude oil fractions (known as hydro-desulphurisation or HDS), the
conversion of natural gas or coal into virtually sulphur-free liquid fuels via
the Fischer-Tropsch reaction (known as the GTL and CTL processes respectively),
and the transformation of biogas (waste methane) into syngas - the building
block of liquid fuels.

The second platform relates to chemical reactions involving a liquid containing
a renewable fuel, such as methanol, ethanol or glycerol, and dilute hydrogen
peroxide. The company's novel catalyst can be used to release hydrogen gas from
this liquid, instantaneously starting from room temperature. This groundbreaking
Instant Hydrogen technology has the potential to significantly accelerate the
commercial adoption of fuel cells in the portable and other mobile markets, by
providing the much needed source of cheap, safe, transportable hydrogen.

Another of the company's catalysts can be used to produce steam at temperatures
between 100 degrees C and 800 degrees C+ instantaneously starting from room
temperature, from a liquid fuel containing dilute hydrogen peroxide and either
an alcohol, sugar, glycerol, starch or formic acid. Such Instant Steam could
have important applications in a broad range of markets, from cleaning and
disinfecting, to green energy in the form of motive power or electricity.
